Question 1

Calculate the solubility of Cu(OH)₂ in a solution buffered at pH = 7.46. (K_sp = 1.6 × 10^–19)

◦ 2.9 × 10^–7M
◦ 5.5 × 10^–13M
◦ 1.9 × 10^–6M
◦ 8.3 × 10^–14M
◦ None of these are correct.

Question 2

Chromate ion is added to a saturated solution of Ag₂CrO₄ to reach 0.67 M CrO₄^2–. Calculate the final concentration of silver ion at equilibrium (K_sp for Ag₂CrO₄ is 9.0 × 10^–12).

◦ 1.8 × 10^–6M
◦ 3.7 × 10^–6M
◦ 5.2 × 10^–6M
◦ 6.7 × 10^–12M
◦ 2.6 × 10^–6M
