We’re being asked to determine which point(s) a–d represent(s) the H₂X/HX– buffer region, given the following titration curve for the titration of 1.00 L of 1.00 M diprotic acid H₂A with NaOH:

Since H₂A is a diprotic acid, this means it has two equivalence points.

Recall that the equivalence point is the point in a titration curve where the pH increases abruptly. In the given titration curve, the two equivalence points are represented by points b and d:
