Question 1:
What is a neutralization reaction? Give some examples.
Answer 1:
When the effect of a base is nullified by an acid and vice versa, it is called neutralization reaction. In general, a neutralization reaction is written as:
Base + Acid ―> Salt + Water
Examples:
(a) Aqueous solution of base, NaOH is neutralized by aqueous hydrochloric acid.

(b) Aqueous solution of sulphuric acid is neutralized by aqueous solution of sodium hydroxide.

Board exams may include application-based questions that require students to apply their knowledge of acids, bases, and salts to solve real-life problems or scenarios. Understanding the chemical reactions involved in neutralization and salt formation is important for answering questions about the preparation and properties of salts. Beyond rote memorization, this chapter emphasizes conceptual understanding. Students should be able to explain the properties and behavior of acids, bases, and salts.

Question 2:
An alkali is an important base used for the laboratory work. Name the base and state how it can be prepared from common salt? What is this process called?
Answer 2:
An important alkali commonly needed for laboratory work is sodium hydroxide. It can be prepared from sodium chloride by the process of electrolysis. This is called chlor-alkali process.
Electrolysis of aqueous solution of sodium chloride: When electricity is passed through an aqueous solution of sodium chloride commonly called brine, it decomposes into chloride and sodium. Sodium is collected at the cathode where it reacts with water to form sodium hydroxide. Chlorine is formed at the anode and is collected as a gas.

Cathode:

At Anode:

The overall reaction is

Question 1:
(a) How does baking soda helps to make cakes and bread soft and spongy? OR
Give reason: cake rise on adding baking powder.
(b) Write chemical equation for its preparation.
Answer 1:
(a) On heating , sodium bicarbonate decomposes to produce carbon dioxide. This causes biscuits and cakes etc. to expand and become light. The other constituents act as preservatives.
(b)

Question 2:
Why does bleaching powder smell strongly of chlorine?
Answer 2:
Bleaching powder smells strongly of chlorine because it slowly reacts with carbon dioxide of air to evolve chlorine gas.

In summary, NCERT Class 10 Science Chapter 2, Acids, Bases, and Salts, is important for board exams because it covers foundational concepts in chemistry and offers practical applications. Students should focus on understanding the principles, mastering problem-solving skills, and being able to apply their knowledge to various scenarios to excel in the examination.
