Calculate the total concentration of lead dissolved ([Pb]total) in a solution saturated with PbI2(s) and containing dissolved I- with a concentration of [I-] = 0.294 M. The solubility of lead is governed by the reactions shown below.
PbI2(s) <--> Pb2+ + 2I- Ksp=7.9E-9Pb2+ + I- <--> PbI+ K1=1.0E2Pb2+ +2I- <--> PbI2(aq) B2=1.4E3Pb2+ +3I- <--> PbI3- B3=8.3E3Pb2+ + 4I- <--> PbI42- B4=3.0E4
