Question 1

Consider the titration of 100.0 mL of 0.100 M H2A (Ka1 = 1.50 × 10–4; Ka2 = 1.00 × 10–8). How many milliliters of 0.100 M NaOH must be added to reach a pH of 5.000?

◦ 41.9 mL
◦ 93.8 mL
◦ 100. mL
◦ 200. mL
◦ 60.0 mL

Question 2

Consider the titration of 100.0 mL of 0.250 M aniline (Kb = 3.8 × 10–10) with 0.500 M HCl. For calculating the volume of HCl required to reach a pH of 8.0, which of the following expressions is correct? (x = volume in mL of HCl required to reach a pH of 8.0)

◦ = [aniline]
◦ [H+] = x
◦ = [aniline]
◦ = [aniline]
◦ None of these are correct.
