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 use the following steps:

### Step 1: Understand the components
Ammonium acetate is a salt formed from a weak acid (acetic acid) and a weak base (ammonium hydroxide). The pKa of acetic acid is given as 4.76, and the pKb of ammonium hydroxide is given as 4.75.

### Step 2: Use the formula for pH of a salt solution
For a salt formed from a weak acid and a weak base, the pH can be calculated using the formula:
\[
