Equilibrium

The $p K_{b}$ of dimethylamine and $p K_{a}$ of acetic acid are 3.27 and 4.77 respectively at $T$ (K). The correct option for the pH of dimethylammonium acetate solution is:

A.8.50
B.5.50
C.7.75✓
D.6.25

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
