Chapter 13, Problem 46E

Acetic acid is a weak acid that reacts with water according to this equation:

${\text{CH}}_3{\text{CO}}_2\text{H}\left(aq\right)+{\text{H}}_2\text{O}\left(aq\right)\rightleftharpoons {\text{H}}_3{\text{O}}^{+}\left(aq\right)+{\text{CH}}_3{\text{CO}}_2{}^{-}\left(aq\right)$

Will any of the following increase the percent of acetic acid that reacts and produces ${\text{CH}}_3{\text{CO}}_2{}^{-}$ ion?

(a) Addition of HCI

(b) Addition of NaOH

(c) Addition of NaCH₃CO₂
