NCERT Solutions for Class 10 Science Chapter 2 Acids, Bases and Salts

 

NCERT Solutions for Class 10 Science Chapter 2 - Acids, Bases and Salts: Acid-base indicators are dyes or mixtures of dyes which are used to indicate the presence of acids and bases. Acidic nature of a substance is due to the formation of H+ (aq) ions in solution. Formation of OH– (aq) ions in solution are responsible for the basic nature of a substance. In Chapter 2 - Acids, Bases and Salts, you will also study when an acid reacts with a metal, hydrogen gas is evolved and a corresponding salt is formed. When a base reacts with a metal, along with the evolution of hydrogen gas a salt is formed which has a negative ion composed of the metal and oxygen. When an acid reacts with a metal carbonate or metal hydrogen carbonate, it gives the corresponding salt, carbon dioxide gas, and water. Acidic and basic solutions in water conduct electricity because they produce hydrogen and hydroxide ions respectively.

Here are the important topics of NCERT Class 10 Science Chapter 2 - Acids, Bases, and Salts mentioned below:

2.1 Understanding the Chemical Properties of Acids and Bases

    2.1.1 Acids and Bases in the Laboratory

    2.1.2 How Do Acids and Bases React with Metals?

    2.1.3 How Do Metal Carbonates and Metal Hydrogencarbonates React with Acids?

    2.1.4 How Do Acids and Bases React with Each Other?

    2.1.5 Reaction of Metallic Oxides React with Acids

    2.1.6 Reaction of Non-Metallic Oxides with Bases

2.2 What Do All Acids and All Bases Have in Common?

2.3 How Strong Are Acids or Bases Solutions?

    2.3.1 Importance of pH in Everyday life

2.4 More About Salts

    2.4.1 Family of Salts

    2.4.2 pH of Salts

    2.4.3 Chemicals from pH of Salt

    2.4.4 Are the Crystals of Salts really Dry?

In NCERT Class 10 Science Chapter 2, you will study that the strength of an acid or an alkali can be tested by using a scale called the pH scale (0-14) which gives the measure of hydrogen ion concentration in a solution. A neutral solution has a pH of exactly 7, while an acidic solution has a pH less than 7 and a basic solution a pH more than 7. Living beings carry out their metabolic activities within an optimal pH range. Mixing concentrated acids or bases with water is a highly exothermic process. Acids and bases neutralize each other to form corresponding salts and water. The water of crystallization is the fixed number of water molecules present in one formula unit of salt. Salts have various uses in everyday life and in industries.

After going through NCERT Solution Class 10 Science Chapter 2, you must be able to answer the following NCERT questions which are mentioned below:

Q1. Are plants and animals pH sensitive?

Q2. What is the pH of the soil in your backyard?

Q3. Plaster of Paris should be stored in a moisture-proof container. Explain why?

Q4. What is a neutralization reaction? Give two examples.

Q5. Give two important uses of washing soda and baking soda.

If you have any query then don't worry, NCERT Solutions for Class 10 Science Chapter 2 - Acids, Bases and Salts will help you out.
