The dissociation of ethanoic acid is an equilibrium process which is represented by the equation: #HC_2H_3O_2  H^+ + C_2H_3O_2^-# How will this equilibrium be affected if a base (OH-) is added?

Clearly, addition of base will drive the equilibrium to the right.


#H_3C-C(=O)OH + ""^(-)OH rightleftharpoons H_3C-CO_2^(-) + H_2O#

Thus addition of stoichiometric sodium hydroxide will yield stoichiometric sodium acetate. Sodium acetate still participates in the equilibrium reaction.
