Statement: The addition of a small amount of a 'neutral' electrolyte (one that does not share a common ion) such as NaCI to a dilute solution of acetic acid, will cause an increase in the degree of dissociation of the acid.
Explanation: Due to the increased ionic strength, the mean ionic activity coefficient of `H_(3)O^(+)` and `CH_(3)COO^(-)` will increase.
