Here we will consider some reactions of a weak acid (HA) and a weak base (in this case, the conjugate of A). Recall that in water acids and bases undergo the following reactions: HA+ H20 H30 + A AH20 OH HA and Write expressions for K, and Kb 1) 2) Write a balanced equation for the reaction of a weak acid (HA) with a strong base, OH- (From, for example NaOH, which dissociates completely to OH in solution). Write an expression for Keq. Do you expect Keg to be small or large for this reaction? 3) Write a balanced equation for the reaction of a weak base (A) with a strong acid, H+, (From, for example, HCl which dissociates completely to Ht in solution). Write a balanced equation for this reaction. Do you expect Keg to be small or large for this reaction? 4) How do your Keg for each reaction compare to your expressions for Ka and Kb?
