Question

An aqueous solution of ammonium chloride is:

• A. Neutral
• B. Acidic
• C. Basic
• D. None of these

Hint:

A salt derived from a strong acid and a weak base forms an acidic solution, while one from a strong base and weak acid forms a basic solution.

Answer 1

The Correct Option is B

Step 1: Understanding the nature of ammonium chloride solution. Ammonium chloride (NH\(_4\)Cl) is a salt derived from a strong acid (HCl) and a weak base (NH\(_4\)OH). When dissolved in water, it hydrolyzes to release \( H^+ \) ions, making the solution acidic. \[ NH_4Cl \rightarrow NH_4^+ + Cl^- \] \[ NH_4^+ + H_2O \rightarrow NH_3 + H_3O^+ \]
Step 2: Explanation of incorrect options.
- Neutral: Only salts of strong acids and strong bases are neutral.
- Basic: Ammonium chloride solution is acidic, not basic.
