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: 90% (147 ratings) ###### Problem Details
