Q.
The $pK_{a}$ of acetic acid and $pK_{b}$ of $NH_{4}OH$ are 4.75 and 4.75 respectively. Find the pH of ammonium acetate solution?

Solution:
Ammonium acetate is a salt of weak acid and weak base.
So pH is given as
$pH=\frac{1}{2}\left(p K_{w} + p K_{a} - p K_{b}\right)$
$=\frac{1}{2}\left(14 + 4.75 - 4.75\right)$
$=7$
