What would happen if the equilibrium of a weak acid dissociation reaction were upset?

A. The reaction would shift to balance the change.

B. The Ky of the reaction would change.

C. The reaction would not return to equilibrium.

D. Equilibrium concentrations would not change.

The reaction would shift to balance the change.

Explanation: When an uncharged weak acid is added to water, a homogeneous equilibrium forms in which aqueous acid molecules, HA(aq), react with liquid water to form aqueous hydronium ions and aqueous anions, A-(aq). The latter are produced when the acid molecules lose H+ ions to water.
