Question

A solution is made by mixing 47.0 mL of 2.88 M Pb(NO₃)₂ with 20.0 mL of 1.79 x 10^-3 M NaI. K_sp for PbI₂(s) is 9.8 x 10^-9.

a) Will a solid form? Show reasoning?


b)   If you answered yes to part a) how many grams of PbI₂(s) will form?


c) What are the concentrations of [Pb²⁺], [I^-], [NO₃^-], and [Na⁺] at equilibrium?
