Problem

19.0 mL of 0.126 M diprotic acid (H 2A) was titrated with 0.1017 M KOH. The acid ionization constants for the acid are Ka1= 5.2x10-5 and Ka2= 3.4x10-10.

a. At what added volume in mL of base does the first equivalence point occur?

b. At what added volume in mL of base does the second equivalence point occur?
