Question

Which of the following forms an acidic solution on hydrolysis?

• A. CH₃COONa
• B. NH₄Cl
• C. KCL
• D. CH₃COOK

Answer 1

Answer:

B. NH₄Cl

NH₄Cl (ammonium chloride) forms an acidic solution on hydrolysis.

NH₄Cl + H₂O → NH₄OH + HCl

The ammonium ion (NH₄⁺) is a weak acid and hydrolyzes to form ammonia (NH₃) and hydrogen ions (H⁺), making the solution acidic.
