An aqueous solution of `NH_4F ` is …………….

Explanation

To solve the question regarding the nature of an aqueous solution of ammonium fluoride (NH₄F), we can follow these steps:

### Step 1: Identify the Components of Ammonium Fluoride
Ammonium fluoride is a salt formed from the neutralization reaction between ammonium hydroxide (NH₄OH) and hydrofluoric acid (HF).

### Step 2: Determine the Strength of the Acid and Base
- **Ammonium Hydroxide (NH₄OH)**: This is a weak base.
- **Hydrofluoric Acid (HF)**: This is a weak acid but stronger than ammonium hydroxide.
