FAQs on Neutralization in Our Daily Life - Acids, Bases and Salts, Class 7, Science

Question 1

1. What is neutralization?

Accepted Answer

Ans. Neutralization is a chemical reaction that occurs when an acid and a base react with each other to form a salt and water. It is a process that helps in neutralizing the acidic or basic properties of a substance.

Question 2

2. How does neutralization occur in our daily life?

Accepted Answer

Ans. Neutralization occurs in our daily life in various ways. For example, when we take antacid tablets to relieve acidity, the basic components in the tablet neutralize the excess acid in our stomach. Similarly, when we use baking soda to neutralize the acidic taste in food, it reacts with the acid present in the food and makes it less acidic.

Question 3

3. What are some common examples of neutralization reactions in our daily life?

Accepted Answer

Ans. Some common examples of neutralization reactions in our daily life include the reaction between an antacid tablet and stomach acid, the reaction between baking soda and vinegar to create carbon dioxide gas, and the reaction between toothpaste and the acids in our mouth to prevent tooth decay.

Question 4

4. How does neutralization help in cleaning products?

Accepted Answer

Ans. Neutralization plays a crucial role in cleaning products. Many cleaning products, such as toilet cleaners and drain cleaners, are highly acidic or basic. When these products come into contact with dirt or stains, the acidic or basic properties help in breaking down the dirt. However, after the cleaning process, neutralization is necessary to ensure that the residue left behind is neither acidic nor basic, making the surface safe for use.

Question 5

5. Can you explain the role of neutralization in agriculture?

Accepted Answer

Ans. Neutralization is important in agriculture to maintain the pH balance of the soil. Different crops require specific pH levels for optimal growth. If the soil becomes too acidic or too basic, it can affect the availability of nutrients to the plants. Farmers often use lime, which is basic in nature, to neutralize acidic soil. This helps in creating a favorable environment for plant growth and ensures better crop yield.
