Question 1

Calculate the solubility of Cu(OH)2 in a solution buffered at pH = 7.46. (Ksp = 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 CrO42–. Calculate the final concentration of silver ion at equilibrium (Ksp 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
