Consider a 0.71 M solution of each of the following salt dissolved in distilled water. Will the solution by basic, neutral, or acidic?

KI=
NH4NO2=
(CH3CH2)3NHNO2=
(CH3CH2)2NH2ClO4=

    All of this hinges on whether the cation or anion act as acids or bases when dissolved in H2O.
    For salts of strong acids and strong bases (example KI) neither is hydrolyzed and the solution should be neutral.
    For salts of weak acids and weak bases (examples are #2 and #3), compare Ka for acid and Kb for base. The stronger one dictates if the solution is acid or basic. If Ka = Kb the soln will be neutral.

    For the last one, it is salt of weak base and strong acid; the soln will be acid.
