Question

22.0 mL of 0.127 M diprotic acid (H2A) was titrated with 0.1017 M KOH. The acid ionization constants for the acid are Ka1 = 5.2 × 10^(-5) and Ka2 = 3.4 × 10^(-10). At what added volume of base does the first equivalence point occur? Express your answer to three significant figures.

Step 1

Given volume of diprotic acid = 22.0 mL = 0.022 L Molarity of diprotic acid = 0.127 M Total moles of diprotic acid = volume x molarity Total moles of diprotic acid = 0.022 L x 0.127 mol/L Show more…
