The `pK_(a)` of acetic acid and `pK_(b)` of ammonium hydroxide are `4.76` and `4.75` respectively. Calculate the pH of ammonium acetate solution.

Explanation

To calculate the pH of an ammonium acetate solution, we can follow these steps:

### Step 1: Identify the given values
- The \( pK_a \) of acetic acid (CH₃COOH) = 4.76
- The \( pK_b \) of ammonium hydroxide (NH₄OH) = 4.75

### Step 2: Understand the nature of the salt
Ammonium acetate (CH₃COONH₄) is formed from a weak acid (acetic acid) and a weak base (ammonium hydroxide). The pH of a solution of a salt formed from a weak acid and a weak base can be calculated using the formula:
