Question

Which of the following is an acidic salt?

• A. NaCl.
• B. NaHSO$_4$.
• C. Na$_2$SO$_4$.
• D. KCN.

Hint:

Acidic salts form when a polybasic acid (like sulfuric acid) is only partially neutralized by a base.

Answer 1

The Correct Option is B

An acidic salt is formed when a strong acid and a weak base react. Sodium bisulfate ($NaHSO_4$) is an acidic salt because it contains an ionizable hydrogen ion ($H^+$), making the solution acidic.
