Answer: d. Rs. 6,000
(4000+7000+3000+x) ÷ 4 = 5000
14000+x = 5000 × 4
x = 20000-14000
x = 6000
4. What is the main criterion used by the World Bank in classifying different countries? What are the limitations of this criterion, if any?
The World Bank employs per capita income as a classification method for various countries. Per capita income is derived by dividing the total income of a country by its population. According to the World Bank, countries with a per capita income of US$955 or below for the year 2017 are classified as low-income countries.
However, this criterion has certain limitations:
1. Ignoring Key Factors: The classification solely relies on per capita income and overlooks critical indicators such as literacy rate, infant mortality rate, and healthcare facilities, which are crucial for assessing a country’s overall development and well-being.
2. Neglecting Income Inequality: The World Bank’s classification fails to consider information regarding the unequal distribution of income within a country. Inequality can significantly impact the socio-economic conditions of its citizens, influencing overall development.
3. Limited Scope: The per capita income criterion does not encompass the broader complexities of an economy and may not fully reflect a country’s development status. Economic development is influenced by numerous interconnected factors that extend beyond income levels alone.
To gain a comprehensive understanding of a country’s development, it is essential to consider a more inclusive approach that takes into account multiple indicators and factors affecting the well-being of its population.
5. In what respects is the criterion used by the UNDP for measuring development different from the one used by the World Bank?
The UNDP (United Nations Development Programme) employs a distinct criterion compared to the World Bank for country comparisons. Unlike the World Bank, which primarily uses per capita income to measure development, the UNDP takes a more comprehensive approach.
UNDP’s criterion considers three key indicators to assess development:
1. Educational Level: The educational level of the people within a country is a crucial factor in determining development. Education empowers individuals, enhances their skills, and contributes to overall human development.
2. Health Status: The health status of a population is another vital aspect of development. Factors such as life expectancy, infant mortality rate, and access to healthcare services play a significant role in assessing a country’s well-being.
3. Per Capita Income: While UNDP considers per capita income like the World Bank, it also integrates it with education and health indicators for a more holistic evaluation of development.
This approach by UNDP offers a more comprehensive and nuanced perspective on development, taking into account multiple dimensions that impact the quality of life and well-being of a country’s citizens. By considering education, health, and income together, UNDP’s criterion provides a more inclusive understanding of a country’s development status.
6. Why do we use averages? Are there any limitations to their use? Illustrate with your own examples related to development.
Calculating averages is a useful method for estimating and comparing different aspects across countries with varying populations. However, there are limitations to relying solely on averages, as they may not provide a complete picture of the income disparities within a country or state.
Let’s illustrate this with an example of two countries, A and B, each having 5 people:
In Country A, the incomes of the five individuals are Rs. 23,000, Rs. 22,000, Rs. 23,500, Rs. 28,000, and Rs. 25,000. The average income of Country A would be Rs. 24,300.
In Country B, the incomes of the five individuals are Rs. 1,50,000, Rs. 22,000, Rs. 50,000, Rs. 4,000, and Rs. 2,500. The average income of Country B would be Rs. 45,700.
While the average income of Country B appears higher than that of Country A, it doesn’t account for the significant disparity in income distribution within each country. In Country B, there seems to be a wide variation in incomes, with some individuals earning substantially higher than others. Conversely, Country A appears to have a more evenly distributed income among its population.
This example highlights that relying solely on average income figures may overlook the inequalities in income distribution within countries. To obtain a comprehensive understanding of economic conditions, it is crucial to consider additional factors, such as income distribution and the overall well-being of the population, to gain a more accurate assessment of a country’s economic situation.
7. Kerala, with lower per capita income, has a better human development ranking than Haryana. Hence, per capita income is not a useful criterion at all and should not be used to compare states. Do you agree? Discuss.
Despite having a lower per capita income, Kerala outperforms Haryana in terms of human development ranking. This indicates that per capita income alone is not a comprehensive criterion for comparing states. Kerala’s superior human development ranking can be attributed to factors like higher literacy rates, lower infant mortality rates, and better healthcare facilities compared to Haryana.
Per capita income merely calculates the average income of a state’s population without considering other crucial factors that contribute to overall development. In the case of Kerala and Haryana, the focus on per capita income alone fails to reflect the significant disparities in social indicators and human well-being.
To make accurate and meaningful comparisons between states, it is essential to consider a holistic set of indicators that encompass economic, social, and human development aspects. These include factors such as literacy rates, access to quality healthcare, education facilities, and infant mortality rates, which provide a more comprehensive picture of a state’s overall development and well-being.
8. Find out the present sources of energy that are used by the people in India. What could be the other possibilities fifty years from now?
Currently, people in India primarily rely on sources of energy such as firewood, coal, petroleum, crude oil, and natural gas. However, looking ahead to the next fifty years, there is significant potential for utilizing renewable sources like solar energy and wind energy to fulfill our diverse energy needs. Embracing these sustainable alternatives is crucial as the continued reliance on conventional energy sources could deplete precious natural resources, leaving future generations at a disadvantage. By transitioning towards renewable energy, we can ensure a greener and more sustainable future for all, preserving our planet’s resources for the well-being of generations to come.
9. Why is the issue of sustainability important for development?
Sustainable development is the responsible utilization of natural resources to meet the needs of both present and future generations. The concept of sustainability holds great significance for overall development because the careful management of natural resources ensures their availability for the well-being of future generations. Failing to use resources judiciously may lead to their depletion, hindering the progress and development of a country. Therefore, embracing sustainable practices is essential to ensure a harmonious balance between development and preservation, securing a prosperous and thriving future for all.
10. “The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person.” How is this statement relevant to the discussion of development? Discuss.
Development relies not solely on a country’s economic factors but also on the availability of resources for its people. The saying, “The Earth has enough resources to meet the needs of all but not enough to satisfy the greed of even one person,” is highly pertinent to a country’s development as natural resources are finite. Responsible utilization of these resources is crucial to meet present needs without compromising the needs of future generations. It is incumbent upon society to use resources wisely, prioritizing needs over greed. Failure to do so could lead to the exhaustion of resources, ultimately hampering a country’s development. Embracing sustainable practices ensures a prosperous future for all.

Land Utilisation
Land resources find application in the following purposes:
1. Forests: Land is allocated for the growth and preservation of forests, vital for ecological balance and biodiversity conservation.
2. Land not available for cultivation: This category includes two subtypes:
a) Barren and wasteland: Land that is unsuitable for agricultural activities due to its arid or unproductive nature.
b) Land put to non-agricultural uses: Land utilized for non-farming purposes such as residential, industrial, or infrastructural developments.
3. Fallow lands: These are lands that are temporarily left uncultivated to regain fertility or due to seasonal reasons.
4. Other uncultivated lands (excluding fallow land): Lands that are not cultivated, excluding those explicitly categorized as fallow.
5. Net sown area: The total land area under cultivation, which excludes the area under fallow and uncultivated land.
Understanding and efficiently utilizing land resources across these diverse purposes are essential for sustainable development and optimal land management.
Land Use Pattern in India
The utilization of land is influenced by two main sets of factors:
1. Physical Factors: These encompass various elements that are inherent to the land itself, such as topography (terrain features and elevation), climate (temperature, precipitation, etc.), and soil types (fertility, composition, etc.). These physical characteristics significantly impact the suitability and productivity of the land for various activities.
2. Human Factors: These factors relate to human interactions and decisions concerning land use. They include population density (the concentration of people in a specific area), technological capability (the level of technology available for land development and utilization), as well as culture and traditions, which influence the practices and preferences related to land use in a given society.
The interplay between these physical and human factors shapes how land is allocated and utilized for different purposes, ranging from agriculture and settlements to industrial and recreational activities.

Acids Bases and Salts Class 10 Notes of NCERT Science Ch. 2
Acids Bases and Salts Class 10 Notes: A salt is created through the replacement of hydrogen ions by a metal or an ammonium ion in the precens of acid. A substance referred to as a base undergoes a reaction with an acid, resulting in the production of water and salt exclusively. Consequently, the combination of an acid and a base leads to the formation of a salt.
Household cleaning products are used to remove oil from windows and floors contain bases. Bases found in items like soaps, toothpaste, egg whites, dishwashing liquids, and household ammonia.
This article will give you a overview and quick short notes on class 10 chapter 2: Acid bases and salts.
CBSE Class 10 Science Notes Chapter 2 Acids Bases And Salts
Acids Bases and Salts Class 10 Notes
Introduction of Acid Base and Salts: Short Notes
An acid is defined as a substance that exhibits a sour taste when dissolved in water, turns blue litmus paper to red, and has the ability to neutralize bases. Conversely, a base is a substance whose aqueous solution tastes bitter, turns red litmus paper to blue, and can neutralize acids. On the other hand, salt is a neutral substance that does not have any impact on litmus paper when dissolved in an aqueous solution.
Acids Bases and Salts can be classified based on:
a) Composition: This includes elements, compounds, and mixtures.
b) State: Matter can exist in the form of solids, liquids, or gases.
c) Solubility: Matter can be categorized as suspensions, colloids, or solutions based on its ability to dissolve.
Mixtures can be further classified as homogeneous or heterogeneous, depending on the uniformity of their composition. Compounds, on the other hand, can be categorised as covalent or ionic compounds based on the types of chemical bonds present within them.
What Is an Acid, Base and Salts
An acid is characterised as any substance that contains hydrogen and has the ability to donate a proton, which is a hydrogen ion, to another substance. On the other hand, a base refers to a molecule or ion that can accept a hydrogen ion from an acid. Acidic substances are commonly recognised by their sour taste, which is a distinctive characteristic.
Ionisable and Non-Ionisable Compounds
As per chapter 2 of class 10 Ionizable compounds are substances that have the ability to undergo ionization, which is the process of forming ions by gaining or losing charged particles (usually electrons or protons) when dissolved in a solvent like water. In other words, ionizable compounds can dissociate into ions in solution.
On the other hand, non-ionizable compounds are substances that do not readily undergo ionization when dissolved in a solvent. These compounds remain predominantly in their molecular form and do not dissociate into ions.
Arrhenius’ Theory of Acids and Bases
According to the Arrhenius definition, an acid is a substance that, when dissolved in water, dissociates to produce H+ (aq) or H3O+ ions. Conversely, an Arrhenius base is a substance that, when dissolved in water, dissociates to yield OH− ions.
Examples:
Acids:
- Hydrochloric acid (HCl)
- Sulphuric acid (H2SO4)
- Nitric acid (HNO3)
Bases:
- Sodium hydroxide (NaOH)
- Potassium hydroxide (KOH)
- Calcium hydroxide (Ca(OH)2)
Bronsted Lowry Theory
A Bronsted acid is defined as a substance that donates an H+ (aq) ion in a chemical reaction. Conversely, a Bronsted base is a substance that accepts an H+ (aq) ion.
Example:
In the reaction: HCl (aq) + NH3 (aq) → NH+4(aq) + Cl− (aq)
- HCl acts as a Bronsted acid because it donates an H+ (aq) ion.
- Cl− is the conjugate base of HCl because it remains after the acid donates its H+ (aq) ion.
- NH3 acts as a Bronsted base because it accepts the H+ (aq) ion from HCl.
- NH+4 is the conjugate acid of NH3 because it is formed after accepting the H+ (aq) ion.
Physical Test for Acid and Base
Two physical tests can be employed to identify an acid or a base.
a. Taste: An acid typically has a sour taste, while a base has a bitter taste. However, this method of taste is not recommended as it can be unsafe due to potential contamination or corrosiveness of acids and bases.
Example: Compounds like curd, lemon juice, orange juice, and vinegar possess a sour taste because they contain acids. Baking soda, on the other hand, has a bitter taste and serves as an example of a base.
b. Effect on Indicators by Acids and Bases: Indicators are chemical substances that undergo a change in their physical properties, such as color or odor, when in contact with an acid or a base. The following are commonly used indicators and the colors they exhibit:
a) Litmus:
- In a neutral solution: Purple
- In an acidic solution: Red
- In a basic solution: Blue
Litmus is available in the form of paper strips, with red litmus and blue litmus variants. An acid turns a moist blue litmus paper to red, while a base turns a moist red litmus paper to blue.
b) Methyl orange:
- In a neutral solution: Orange
- In an acidic solution: Red
- In a basic solution: Yellow
c) Phenolphthalein:
- In a neutral solution: Colorless
- In an acidic solution: Remains colorless
- In a basic solution: Pink
These indicators can be used to determine whether a substance is acidic or basic based on the observed color change.
Acid-Base Reactions for Class 10 Students
An acid-base neutralization reaction takes place when an acid reacts with a base. The outcome of this reaction is the formation of salt and water as the end products. In the standard approach, an acid-base neutralization reaction is represented as a double-replacement reaction.
Class 10 Reactions of Acids and Bases
a) Reaction of acids and bases with metals
Acids, in general, react with metals to produce salt and hydrogen gas. Bases, in general, do not react with metals and do not produce hydrogen gas.
Acid + active metal → salt + hydrogen + heat
2HCl + Mg → MgCl2 + H2 (↑)
Hydrochloric acid + Magnesium → Magnesium chloride + Hydrogen
Base + metal → salt + hydrogen + heat
2NaOH + Zn → Na2ZnO2 + H2 (↑)
Sodium hydroxide + Zinc → Sodium zincate + Hydrogen
A more reactive metal displaces the less reactive metal from its base.
2Na + Mg (OH) 2 → 2NaOH + Mg
Sodium + Magnesium hydroxide → Sodium hydroxide + Magnesium
b) Reaction of acids with metal carbonates and bicarbonates
Acids produce carbon dioxide, as well as metal salts and water, when they react with metal carbonates or metal bicarbonates. Sodium chloride, carbon dioxide, and water are formed when sodium carbonate interacts with hydrochloric acid. Allowing carbon dioxide gas to travel through lime water turns it milky.
Acid + metal carbonate or bicarbonate → salt + water + carbon dioxide.
2HCl + CaCO3 → CaCl2 + H2O + CO2
H2SO4 + Mg (HCO3)2 → MgSO4 + 2H2O + 2CO2
Effervescence indicates the liberation of CO2 gas.
c) Reaction of Acid with Base given in class 10
1. Reaction of metal oxides and hydroxides with acids
Metal oxides or metal hydroxides are basic in nature.
Acid + base → salt + water + heat
H2SO4 + MgO → MgSO4 + H2O
2HCl + Mg (OH) 2 → MgCl2 + 2H2O
2. Reaction of non-metal oxides with bases
Non-metal oxides are acidic in nature
Base + Nonmetal oxide → salt + water + heat
2NaOH + CO2→ Na2CO3 + H2O
3. Reaction of acids and base
A very common acid is hydrochloric acid. The reaction between strong acid, says hydrochloric acid and strong base say sodium hydroxide, forms salt and water. The complete chemical equation is shown below.
HCl (strong acid) + NaOH (strong base) → NaCl (salt) + H2O (water)
Water:
Water itself is a neutral substance and does not exhibit acidic or basic properties. However, it plays a crucial role in the dissociation of acids and bases when they are added to it. Acids and bases dissociate into their respective ions when dissolved in water, allowing them to conduct electricity.
Difference between a Base and an Alkali:
Base:
- Bases can undergo a neutralization reaction with acids.
- They are composed of metal oxides, metal hydroxides, metal carbonates, and metal bicarbonates.
- Most bases are insoluble or only slightly soluble in water.
Alkali:
- An alkali refers specifically to an aqueous solution of a base, primarily consisting of metallic hydroxides.
- Alkalis readily dissolve in water and dissociate to produce OH− ions.
- It’s important to note that while all alkalis are bases, not all bases are alkalis. The term “alkali” specifically applies to bases that are soluble in water and form alkaline solutions.
Hydronium Ion
Acids Bases and Salts Class 10 Notes
A hydronium ion is created when a hydrogen ion (H+) accepts a lone pair of electrons from the oxygen atom of a water molecule. This interaction leads to the formation of a coordinate covalent bond between the hydrogen ion and the water molecule.
Dilution: Dilution refers to the process of decreasing the concentration of a solution by adding more solvent, usually water. This addition of solvent is typically an exothermic process, releasing heat. When diluting an acid, it is important to add the acid to water gradually, and not the other way around, to prevent potential splattering or hazardous reactions.
Strength of Acids and Bases: Strong acid or base: A strong acid or base is characterized by complete dissociation in water, where all the molecules of a given amount fully separate into their respective ions, resulting in the presence of H+(aq) ions for acids and OH−(aq) ions for bases.
Weak acid or base: In contrast, a weak acid or base only partially dissociates in water, with only a few of the molecules from a given amount breaking apart to form their respective ions. This results in the presence of H+(aq) ions for acids and OH−(aq) ions for bases, but in smaller quantities compared to strong acids or bases.
pH
A universal indicator is a type of pH indicator that provides a pH range from 0 to 14, allowing it to indicate the acidity or alkalinity of a solution. It changes color depending on the pH value of the solution, providing a visual representation of its acid-base nature.
PH Scale for Acids Bases and Salts
A neutral solution, which is neither acidic nor alkaline, has a pH value of 7.
The pH of a solution can be calculated using the equation pH = -log10[H+]. In pure water, the concentrations of both hydrogen ions ([H+]) and hydroxide ions ([OH-]) are equal to 10^-7 mol/L. Therefore, the pH of pure water is 7.
The pH scale spans from 0 to 14, where values below 7 indicate an acidic solution, values above 7 indicate a basic (alkaline) solution, and a pH of 7 represents a neutral solution.
Importance of pH in Everyday Life: Class 10 Notes
1. pH sensitivity of plants and animals:
Plants and animals exhibit sensitivity to pH levels. Vital biological processes such as food digestion, enzyme functions, and hormonal activities rely on specific pH values for proper functioning.
2. pH of soil:
For optimal plant growth and cultivation, the pH of soil is ideally maintained between 6.5 and 7.0. This range provides favorable conditions for nutrient availability and absorption by plants.
3. pH in the digestive system:
The digestive process within our stomach occurs at a specific pH range of 1.5 to 4. The acidic environment, influenced by hydrochloric acid (HCl), aids in the breakdown of food. Enzymatic activities during digestion are also dependent on the pH conditions within the stomach.
4. pH in tooth decay:
Tooth decay occurs when teeth are exposed to an acidic environment with a pH of 5.5 and below. Acidic conditions promote the erosion of tooth enamel, leading to decay and cavities.
5. pH in self-defence mechanisms of animals and plants:
Both animals and plants employ acidic substances as a means of self-defense. For instance, bees and plants like nettles secrete highly acidic substances to deter threats. These secreted acidic substances possess specific pH levels that contribute to their defensive properties.

Frequently Asked Question – FAQ on Acids Bases and Salts Class 10 Notes
Q 1. In the absence of water, acids do not exhibit their characteristic acidic behaviour.
Ans: Acids require water to display their typical acidic behavior due to a process known as ionization or dissociation. Acids release positively charged hydrogen ions (H+) into the water. These hydrogen ions are responsible for the acidic properties of the solution, as they can donate protons to other substances, leading to various acid-base reactions.
In the absence of water, there is no medium for the acids to dissociate into ions. Therefore, without water, acids cannot release hydrogen ions, and as a result, they do not exhibit their usual acidic characteristics such as the ability to lower pH, react with bases, or corrode certain materials.
Q 2. What are the three properties of Acids bases and salts?
Ans: The three main properties of acids are:
1. Sour taste: Many acids have a sour taste. Tasting acids is not recommended due to their potential for high corrosiveness and harm to health.
2. Acidic pH: Acids typically have a pH value lower than 7. The pH scale ranges from 0 to 14, considering 7 as neutral, and classifying values below 7 as acidic and values above 7 as alkaline (basic). The lower the pH value, the stronger the acid.
3. Acid-base reactions: Acids have the ability to react with bases to form salts and water in a process known as neutralization. In these reactions, acids donate hydrogen ions (H+) to bases, which then accept the ions to form water. This neutralization reaction results in the reduction of acidic or basic properties, respectively.
It’s important to handle acids with care, as some can be highly corrosive and pose significant risks to health and safety. When handling acids, it’s essential to prioritize safety and follow proper laboratory protocols.
Q 3. Write the pH range for acids and alkalis?
Ans: The pH scale ranges from 0 to 14, where:
- pH values below 7 indicate acidity
- pH 7 is neutral
- pH values above 7 indicate alkalinity (also known as basic).
Q 4. What is the chemical name of gypsum?
Ans: The chemical name of gypsum is “calcium sulfate dihydrate.” The gypsum (CaSO4·2H2O) made up of calcium ions (Ca2+), sulfate ions (SO42-), and two water molecules (H2O) in each unit.
Q 5. What is the common name of the compound CaOCl2?
Ans: The common name of the compound CaOCl2 is “bleaching powder” or “chlorinated lime.” It is a white or pale grayish powder with a strong smell of chlorine.

Nationalism in India Class 10 Notes
World War 1 (1914 -1918)
World War 1, had a profound impact on the world, and India was no exception. While India was a colony under British rule during this period, its involvement in the war was significant. The war brought forth numerous changes and challenges for the Indian subcontinent, shaping its political, social, and economic landscape.
As a part of the British Empire, India was automatically drawn into World War 1. The British government utilized Indian resources, manpower, and finances to support the war effort. Around 1.5 million Indian soldiers were recruited to serve on various battlefronts across the globe, making it the largest voluntary army of that time.
Indian soldiers exhibited tremendous bravery and dedication, playing a vital role in several major battles, including the Battle of Neuve Chapelle, Battle of Ypres, and the Mesopotamian campaign. Their sacrifices were significant, with over 74,000 Indian soldiers losing their lives and many more injured.
The war also had a significant impact on the home front in India. The British government imposed heavy taxes and requisitioned resources, leading to economic hardships and food shortages. Additionally, the war heightened political consciousness among Indians, and demands for self-rule and independence intensified.
India’s involvement in World War 1 became a turning point in the Indian nationalist movement. The war’s promise of democracy and self-determination for all nations highlighted the hypocrisy of British colonial rule. This led to the emergence of more assertive demands for independence and galvanized leaders like Mahatma Gandhi, who initiated nonviolent movements to demand self-rule.
The aftermath of World War 1 had a lasting impact on India’s political landscape. The disillusionment with British promises of self-determination fueled the demand for complete independence, leading to the Non-Cooperation Movement and the Civil Disobedience Movement in the subsequent years.
Satyagraha
As per the NCERT 10th class history book, Satyagraha is derived from the words “Satya” (truth) and “Agraha” (holding on to truth). Mahatma Gandhi launched three regional Satyagrahas, as follows:
1. Champaran: In 1916, Gandhi initiated the first Satyagraha in Champaran, Bihar, encouraging people to protest against the oppressive teenkathiya system (plantation system).
2. Kheda: In 1917, Gandhi organized a Satyagraha in the Kheda district of Gujarat, supporting poor peasants demanding relief from high revenue collection.
3. Ahmedabad: In 1918, a Satyagraha was organized for cotton mill workers in Ahmedabad.
Gandhi Ji based these movements on two principles: truth and non-violence. He believed that pure intentions could render force unnecessary in Satyagraha. Being a practitioner of non-violence, he emphasized that truth and non-violence (Dharma) were potent tools to win any battle. Throughout India’s nationalist struggle, Gandhi upheld this Dharma, as detailed in the 10th class history books.
Rowlatt Act of 1919
Following the regional Satyagrahas, Gandhi decided to launch a nationwide movement. However, in response, the Imperial legislative council passed the Rowlatt Act in 1919, granting the British significant power to suppress political activities and detain political prisoners without trial for two years.
In retaliation, Gandhi initiated a hartal (strike) on 6th April, marking the beginning of India’s workers’ national movement. This led to widespread disruptions, with closed shops, disrupted railways, and telegraph lines. In certain areas, martial law was imposed, and local leaders were arrested, while Gandhi himself was barred from entering Delhi.
On 13th April, during the Baisakhi festival in Amritsar, unaware of martial law, a gathering of people witnessed a tragic incident. General Dyer opened fire upon them, resulting in a large number of casualties to instill fear and awe. This dark episode is etched in the history of India’s nationalist movement.
As mentioned in the chapter “Nationalism in India Class 10,” Gandhi staunchly upheld non-violence. In response to the Jallianwala Bagh massacre, he immediately called off the hartal, adhering to his principles of peaceful resistance.

Non Cooperation and Khilafat
According to the Nationalism in India Class 10 Notes, The Non-Cooperation Movement was launched by Mahatma Gandhi in 1920. It was a nationwide campaign aimed at resisting British rule through nonviolent means.
The movement called for Indians to boycott British institutions, schools, colleges, courts, and civil services, and to withdraw support from the British government. People were urged to adopt swadeshi (buying Indian-made goods) and spin their own cloth using the charkha (spinning wheel) to promote self-reliance.
The Non-Cooperation Movement saw widespread participation from people across different sections of society. It marked a turning point in India’s freedom struggle and brought millions of Indians together in a collective effort for independence.
However, the movement was called off in 1922 after a violent incident at Chauri Chaura, where protestors clashed with police, leading to casualties. Mahatma Gandhi believed that nonviolence was the essence of the movement, and he called it off to avoid further escalation of violence.
Non-Cooperation Movement in Stages
The Non-Cooperation Movement, launched by Mahatma Gandhi in 1920, unfolded in several stages, each marked by distinct activities and events. Here are the key stages of the Non-Cooperation Movement:
1. Launch and Mass Participation (1920):
The Non-Cooperation Movement was officially launched on August 1, 1920, during the special session of the Indian National Congress in Calcutta (now Kolkata). Mahatma Gandhi called for nonviolent non-cooperation with the British government as a means to resist colonial rule. The movement aimed to unite people from all sections of society in a nonviolent struggle for independence.
2. Boycott of Institutions (1920-1921):
During the initial phase, Indians were urged to boycott British institutions, including schools, colleges, and law courts. Lawyers and students withdrew from these institutions, leading to a significant impact on the British administration.
3. Surrender of Titles and Resignation from Government Posts (1920-1922):
Many Indians, especially leaders and government officials, resigned from their posts and returned their titles to the British government. This act symbolized their rejection of British authority and demonstrated their commitment to the cause of independence.
4. Boycott of Foreign Goods and Promotion of Swadeshi (1920-1922):
The Non-Cooperation Movement encouraged Indians to boycott foreign goods and promote the use of swadeshi (Indian-made) products. People began spinning their own cloth using the charkha and boycotted British-manufactured textiles, leading to a surge in the use of Indian textiles.
5. Mass Demonstrations and Protests (1920-1922):
Throughout the movement, mass demonstrations, processions, and public meetings were held across India. These gatherings became platforms for expressing discontent against British rule and demanding self-governance.
6. Suspension of Civil Disobedience (1922):
In 1922, the Non-Cooperation Movement took an unfortunate turn when violent clashes occurred in Chauri Chaura, Uttar Pradesh. A mob attacked a police station, resulting in the death of several police officers. Mahatma Gandhi, who always emphasized nonviolence, was deeply disappointed by the incident. In response, he suspended the movement, believing that nonviolence was essential for its success.
The Non-Cooperation Movement was a pivotal phase in India’s freedom struggle, bringing millions of people together in a nonviolent resistance against British rule. While it was suspended in 1922, its impact continued to inspire future movements, leading India closer to achieving independence in 1947.
Civil Disobedience Movement
In the Nationalism in India Class 10, a significant milestone highlighted is the Civil Disobedience Movement, characterized by the following key features:
1. Advancement from Non-Cooperation: The movement went beyond Non-Cooperation, urging people not only to abstain from cooperation but also to defy colonial laws.
2. Boycott of Foreign Cloth and Picketing of Liquor Shops: People actively boycotted foreign cloth and engaged in picketing liquor shops as acts of protest.
3. Peasants’ Refusal to Pay Revenue and Chowkidar Taxes: Peasants were encouraged to resist paying revenue and chowkidar taxes as a form of civil disobedience.
4. Refusal to Attend English Medium Schools, Colleges, Offices, and Courts: Students, village officials, and lawyers were urged not to attend English medium institutions and colonial offices and courts.
The Civil Disobedience Movement marked a bold step in the struggle for India’s independence, as people engaged in nonviolent resistance and non-cooperation with oppressive colonial laws and institutions.
Beginning of Civil Disobedience
In 1930, Gandhiji initiated the Dandi march to protest against the monopoly rights on salt manufacturing. Together with his supporters, he openly defied the salt law by making salt themselves. This marked the beginning of a civil disobedience movement, aiming to mobilize people from all backgrounds and classes to unite against the oppressive rule of the British Government. The Dandi march became a significant event among other national movements in India.
However, in the present, we observe threats to our society’s framework from negative elements seeking to divide our nation along lines of caste, creed, religion, and class. As responsible citizens, it becomes our duty to safeguard the hard-fought freedom and unity of our nation.
Participants in the Civil Disobedience Movement
The civil disobedience movement witnessed the active involvement of various social groups expressing their discontent with colonial policies. Rich peasant communities joined to combat high revenue policies, while the Indian business classes reacted against restrictive colonial regulations on their businesses. However, the poor peasant and industrial working classes did not participate in significant numbers. One notable aspect of the movement was the remarkable participation of women in picketing and protests, highlighting their crucial role in the struggle for independence.
Limits of the Civil Disobedience Movement
The impact of the civil disobedience movement was relatively limited. Dalits showed minimal participation in the movement, as they focused on seeking political empowerment through increased representation and demanded separate electorates. B.R. Ambedkar led this movement, culminating in the Poona Pact of 1932, despite opposition from Gandhi.
Muslim communities also felt somewhat disconnected from the movement, particularly after the Khilafat movement lost its significance. The apprehension of potential Hindu dominance played a significant role in the minority Muslim communities’ reluctance to respond actively to the movement.
Salt March
The Salt March, also known as the Dandi March, was a significant event during India’s struggle for independence from British colonial rule. It was a nonviolent protest led by Mahatma Gandhi in 1930 to oppose the British-imposed salt tax, which heavily burdened the Indian population and symbolized British economic exploitation.
The Salt March began on March 12, 1930, when Mahatma Gandhi, along with 78 volunteers, embarked on a 240-mile journey from his ashram in Sabarmati, Gujarat, to the coastal town of Dandi. The march lasted for 24 days, covering about 10 miles per day. Thousands of people joined Gandhi along the way, making it a powerful mass movement.
During the march, the participants followed strict principles of nonviolence and civil disobedience. They picked up salt along the seashore, openly defying the British salt laws, which granted the British a monopoly on salt production and taxed the production and sale of salt.
The Salt March garnered widespread attention and support from Indians across the country. It inspired people to boycott British salt and produce their own salt, marking a symbol of defiance against British authority and economic exploitation. This act of civil disobedience demonstrated the power of nonviolent resistance and the unity of the Indian masses in their quest for independence.
The Salt March, along with other civil disobedience movements, put immense pressure on the British government and led to negotiations with Mahatma Gandhi. Ultimately, it played a crucial role in shaping India’s freedom struggle and strengthening the nationalist movement. The Salt March remains a remarkable example of the effectiveness of nonviolent resistance and Gandhi’s leadership in India’s journey towards independence.
Gandhi Irwin Pact
To address the escalating tensions and widespread unrest, Mahatma Gandhi and Lord Irwin engaged in negotiations. The talks culminated in the Gandhi-Irwin Pact, which had the following key provisions:
- Suspension of Civil Disobedience: Gandhi agreed to suspend the Civil Disobedience Movement, calling off the mass protests and non-cooperation activities.
- Participation in Round Table Conference: As part of the pact, the British government agreed to invite Indian representatives to attend the Second Round Table Conference in London. The conference aimed to discuss constitutional reforms and the future of India’s political structure.
- Release of Political Prisoners: In return for suspending the movement, the British government agreed to release political prisoners who were arrested during the Civil Disobedience Movement.
The signing of the Gandhi-Irwin Pact marked a temporary truce between the Indian National Congress, led by Gandhi, and the British government. It provided an opportunity for negotiations and discussions on India’s future political setup. However, the Round Table Conferences did not lead to substantial outcomes, as there were disagreements between the Indian leaders and the British authorities.
Despite the temporary setback in achieving complete independence, the Gandhi-Irwin Pact played a crucial role in providing a platform for discussions and raising international awareness about India’s struggle for freedom. It highlighted Gandhi’s commitment to nonviolence and peaceful negotiations in the pursuit of India’s independence. The pact also paved the way for future negotiations and agreements that ultimately led to India’s independence in 1947.
Development of a Sense of Collective Belonging
The development of a sense of collective belonging played a crucial role in the growth of nationalism. Various cultural processes, including the use of symbols, folklore, and Indian history, contributed to spreading ideas of nationalism. However, some aspects, such as the glorification of a Hindu past, alienated people from other communities.
