Question 3: Draw the titration curve (pH versus mL of NaOHadded) that would be obtained from the titration of 30 mL of a 0.10M solution of an unknown triprotic acid, H3A (Ka1 = 1.26 x 10–3;Ka2 = 5.6 x 10–6; Ka3 = 3.32 x 10–10) with 0.10 M NaOH. Indicatethe volume needed to reach the first, second, and third equivalencepoints and the pH at the half equivalence points for the threetitration regions.
