Consider the graph of #pH# versus volume of solvent added in the appropriate acid base titration...........

Explanation:

chemistry.stackexchange.com

The graph depicts the titration of a strong base with a strong acid...

Well before equivalence, addition of the acid titrant only marginally affects solution #pH#; we are still in the basic regime. Towards equivalence, the #pH# changes dramatically, as the last excess of #HO^-# is neutralized. Beyond equivalence, addition of further titrant only marginally decreases solution #pH#.
