WebAcetic acid, CH 3 CO 2 H, is a weak acid. When we add acetic acid to water, it ionizes to a small extent according to the equation: CH3CO2H(aq) + H2O(l) ⇌ H3O+(aq) + CH3CO2−(aq), giving an equilibrium mixture with most of the acid present in the nonionized (molecular) form. This equilibrium, like other equilibria, is dynamic; acetic acid ...
