Question

The salt which will give an acidic solution on dissolving in water is ______.

Options

• KCl

• NH₄Cl

• Na₂CO₃

• CH₃COONa

Answer 1

The salt which will give an acidic solution on dissolving in water is NH₄Cl.

Explanation:

The Ammonium chloride (NH₄Cl) is a salt formed from a strong acid (HCl) and a weak base (NH₄OH). When dissolved in water, the ammonium ion undergoes cationic hydrolysis to release extra hydrogen ions, which lowers the pH and makes the solution acidic
