NHC2H3O2 is the salt of a weak acid (HOAc; K, -1.8 x 10 M) and a weak base (NH3; K, 1.8 x 105 M). Although we did not learn how to calculate the pH of that kind of solution, you should be able to predict whether the solution would be acidic, basic, or neutral. Do so and explain your reasoning. Compare your expectations to the observed pH of the NHC2H3O2 solution and comment on the agreement.
