Essay
Answer the following questions:
a. Explain why the solubility of carbonates and phosphates is increased by lowering the pH, but the solubility of chlorides is unaffected by lowering the pH.
b. The solubility of copper(II) carbonate is dramatically increased by the addition of NH3, but the solubility of copper(II) phosphate is not. Referring to the data below, explain why.
Ksp for copper(II) carbonate = 2.5 ´ 10-10
Ksp for copper(II) phosphate = 1.4 ´ 10-37
Cu2+(aq) + 4 NH3(aq)
(Kf = 1.1 ´ 1013)
