Acids, Bases & Salts Questions with Solutions

This topic covers acids, bases and salts, their properties, indicators, the pH scale, neutralisation, the acids found in natural substances, and important salts such as common salt, baking soda, washing soda, bleaching powder and plaster of Paris. Questions often ask which acid is found in which substance (citric acid in lemons, lactic acid in curd, formic acid in ant stings and tartaric acid in tamarind), the pH range of acids and bases, and the uses of everyday salts. The pH of pure water is 7, and a pH below 7 means a solution is acidic. Practise the acids, bases and salts questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
