The `pK_(a)` fo 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 given the pK_a of acetic acid and the pK_b of ammonium hydroxide, we can follow these steps:

### Step 1: Understand the Components
We know that ammonium acetate is formed from acetic acid (a weak acid) and ammonium hydroxide (a weak base). The pK_a of acetic acid is given as 4.76, and the pK_b of ammonium hydroxide is given as 4.75.

### Step 2: Use the Relationship Between pK_a, pK_b, and pH
For a salt formed from a weak acid and a weak base, the pH can be calculated using the following formula:
\[
