NCERT Solutions for Class 7 Chapter 2 Acids, Bases and Salts


The combination of acid and base results in the formation of salts which can either be acidic, basic or neutral. This process is known as neutralization. Neutralization is a critical topic concerning the examination. To avoid confusion between acids, bases, and salts make a comparison table of them. An acid is defined as a substance whose water solution tastes sour, turns blue litmus red and neutralizes bases. A substance is called base if its aqueous solution tastes bitter, turns red litmus blue or neutralizes acids. Salt is a neutral substance whose aqueous solution does not affect litmus. Acids, bases and salts are common in our everyday life. It is essential to know its properties to exploit its advantages and to prevent its dangers. From the exam point of view, neutralization and its application are crucial.
