Which of the following salt solutions turns red litmus blue?

Options

ANH ₄ CN
BNH ₄ Cl
CNH ₄ NO ₃
DNaNO ₃

Correct answer

A. NH ₄ CN

Step-by-step solution

The pH of a solution depends on the hydrolysis of a salt. Except NH ₄ CN , all the other salts are products of strong acids HCl or HNO ₃ . Hence, NH ₄ CN turns red litmus blue as HCN is a weak acid.
