Find the concentration of Pb2 in 0.0010 M KI saturated with PbI2. Include activity coefficients in your solubility-product expression. The Ksp of PbI2 is 9.8× 10-9. Hint from sapling below: Including activity coefficients, the solubility-product expression for PbI2 is Ksp = [Pb2+]?Pb2+ [I-]?2I- Ksp for PbI2 is 9.8× 10-9. . Assume that [I-] = 0.0010 M. The ionic strength of 0.0010 M KI can be calculated, then used to find the activity coefficients from a table
