Question 1

A titration of 200.0 mL of 1.05 M H2A was done with 1.00 M NaOH. For the diprotic acid H2A, Ka1 = 2.5 × 10–5, Ka2 = 3.1 × 10–9. Calculate the pH before any 1.00 M NaOH has been added.

◦ 11.71
◦ 4.58
◦ 9.42
◦ 9.16
◦ 2.29

Question 2

A weak acid, HF, is in solution with dissolved sodium fluoride, NaF. If HCl is added, which ion will react with the extra hydrogen ions from the HCl to keep the pH from changing?

◦ OH–
◦ Na+
◦ F–
◦ Na–
◦ None of these are correct.
