Use the Nernst Equation to calculate the concentration of Pb2+ (from the dissolved PbI2 ) in the lead concentration cell based on the average corrected ecell value from part d (table 4).

Given that the solubility product of PbI2 is expressed as Ksp = [Pb2+][I–]2, calculate the Ksp of PbI2 from the concentration of Pb2+ found in Step 6 of the Data Analysis. (Hint: Think about the stoichiometry involved when PbI2 was initially formed
