Well all of these salts are chemically dissociated in aqueous solution....

Explanation:

i.e. #KNO_3(s) stackrel(H_2O)rightleftharpoons K^+ + NO_3^(-)#

Acetate ion undergoes association in an acid-base reaction, but the given equilibrium LIES to the left as we face the page:

#H_3C-CO_2^(-) + H_2O(l) rightleftharpoons H_3C-CO_2H(aq) +HO^-#
