Chapter 16, Problem 39E

What is the (a) degree of ionization and (b) percent ionization of propionic acid in a solution that is 0.45 M CHCH₂COH?

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CO}}_{\text{2}}{\text{H+H}}_2\text{O}\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{\text{+}}{\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}^{\text{-}}\text{pKa=4}\text{.89}$
