Question:

(a) Sketch the titration curve for the titration of 5.00 mL 0.010 m H3AsO4(aq) with 0.010 m KOH(aq), identifying the initial and final points, the stoichiometric points, and each of the halfway points.

(b) What volume of KOH has been added at each stoichiometric point?

(c) Determine the pH at each stoichiometric point. For H3AsO4(aq), pKa1 = 2.25 and pKa2 = 6.77.
