The percent ionization of a weak acid HA is greater in a solution containing the salt NaA than it is in a solution of the weak acid only.

Question

Quizplus · Accepted Answer

The presence of the salt NaA, which contains the conjugate base A-, suppresses the ionization of the weak acid HA due to the common ion effect, leading to a lower percent ionization compared to a solution of the weak acid alone.
