a. Notice that the plot has essentially two titration curves. If the first equivalence point occurs at 100.0 mL NaOH added, what volume of NaOH added corresponds to the second equivalence point?
b. For the following volumes of NaOH added, list the major species present after the OH- reacts completely.
i. 0 mL NaOH added
ii. Beween 0 and 100.0 mL NaOH added
iii. 100.0 mL NaOH added
iv. Between 100.0 and 200.0 mL NaOH added
v. 200.0 mL NaOH added
vi. After 200.0 mL NaOH added
c. If the pH at 50.0 mL NaOH added is 4.0 and the pH at 150.0 mL NaOH added is 8.0, determine the values Ka1 and Ka2 for the diprotic acid.
