Quizplus · Accepted Answer

The equivalence point is where the moles of acid and moles of base are equal, which corresponds to the point where the pH is the greatest. In the titration of a weak acid with a strong base, the equivalence point will occur at a pH greater than 7 due to the formation of a basic salt. Point c corresponds to the point where the pH is the greatest, indicating the equivalence point for the titration of the weak acid. Points a, b, and d correspond to the equivalence points for the titration of a strong acid, which occur at a pH of 7.
