Answer to Question #90453 in Physical Chemistry for holly

Question

Please explain why [H+] is no longer equal to [A-] when a strong base is added to a weak acid.

Answer 1

Solution.

This is a description of one of the features of acid-base titration, the general formula for which is as follows:

H+ + OH- = H2O

[H+] of the acid interact with [OH-] of the base. But in order to maintain balance on the Le Chatelier principle, the acid must additionally dissociate. Therefore, the concentration of [H3O+] will decrease as it is removed from the solution, and [A-] will increase until the acid goes into the layered solution.
