A solution contains 1.0 10 4 M Cu + and 2.0 10 3 M Pb

Question:

A solution contains 1.0 × 10^–4 M Cu⁺ and 2.0 × 10^–3 M Pb²⁺. If a source of I^– is added to this solution gradually, will PbI₂ (K_sp = 1.4 × 10^–8) or CuI (K_sp = 5.3 × 10^–12) precipitate first? Specify the concentration of I^– necessary to begin precipitation of each salt.
