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

In this chapter, you will study about Acids, Bases and Salts in detail. Have you ever
wondered why different things taste differently? Why vinegar tastes sour and why
watermelon tastes sweet? This is because of their chemical composition in the form of
acids, bases and salts.

Acid is a substance that is sour in nature and changes the colour of blue litmus to red.
Base is a substance that is bitter in taste and changes the colour of the red litmus to
blue. You must be wondering what is litmus? Litmus is a natural indicator like turmeric.
Whereas, salt is a neutral substance which is not affected by the litmus test. All these
three substances– acids, bases and salts are termed as ‘Electrolytes’.

An in-depth study of NCERT Solutions for Class 10 Science, Chapter 2 is important to
learn how acids, bases and salts react with air, water and metals.

In Class 10 Science Chapter 2, you will learn – 

Section 2.1 – In this section, you’ll study the chemical properties of acids and bases.
You’ll learn about certain indicators like ‘olfactory’ indicators (like onions, vanilla,
clove) that will help you decide whether a substance is acidic or basic in nature.

Section 2.2 – In this section, you’ll acquire knowledge about the common factors
between all acids and bases. You’ll also learn the reactions that take place in aqueous
solution.

Section 2.3 – In this section, you’ll learn how strong a given acid or a base is by using
the universal indicator – the pH scale. You’ll study about the presence of pH in living
organisms like humans, plants and animals, and also soil. You’ll even study some
naturally occurring acids like vinegar, tamarind, orange and tomato and test the pH
values of various solutions.

Section 2.4 – In this section, you’ll acquire knowledge about different kinds of salts,
preparations, properties and uses of salts, pH of salts and chemical formulae of various
salts. You will learn how to check the solubility of various salts in water and report the
observations. You’ll also study properties and uses of common salt, bleaching powder,
baking soda and washing powder.

In this chapter, you are provided with several activities and examples with their
solutions for a clear understanding of Acids, Bases and Salts. To know more about
