Question 1

Consider the titration of 100.0 mL of 0.10 M H2A (Ka1 = 1.5 × 10–4; Ka2 = 8.0 × 10–7) with 0.20 M NaOH. Calculate the volume of 0.20 M NaOH required to reach an [H+] of 6.0 × 10–4M.

◦ 0 mL
◦ 10. mL
◦ 25. mL
◦ 50. mL
◦ 65. mL

Question 2

Consider the titration of 100.0 mL of 0.10 M H2A (Ka1 = 1.50 × 10–4; Ka2 = 7.82 × 10–7) with 0.20 M NaOH. Calculate the [H+] after 75.0 mL of 0.20 M NaOH has been added.

◦ 1.6 × 10–6M
◦ 1.3 × 10–8M
◦ 3.9 × 10–7M
◦ 7.8 × 10–7M
◦ None of these are correct.
