WebA plot of pH vs volume is known as a titration curve. When the acid HA is titrated with NaOH, the reaction taking place is OH − (aq) + HA (aq) → A − (aq) + H 2 O (l) A polyprotic acid has more than one ionizable proton and each proton results in an equivalence point. As the titration proceeds, the nature of the solution will change.
