Identify the basic salt from the following salts:
(a) Na2CO3 (b) NH4CI (c) NaNO3 (d) KCl
Correct Answer: (a) Na2CO3
Explanation: Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called Basic salts. These are produced by the reaction of a strong base and weak acid. The pH is greater than 7.
Hence, Sodium carbonate (Na2CO3) is a basic salt as it dissolves in water to form NaOH (strong base) and H2CO3 (weak acid).
