2. A) The solubility product, Ks of lead chloride, PbCl2, at 25°C is 1.70 x 10-5. (I) Calculate the concentrations of each ion in mol L-1 in the saturated solution? (Ii) Assuming that there is no effect of ionic force on solubility, estimate the Concentrations of Pb2 + and Cl- in mol L-1 in a 1.00 M NaCl solution. B) Is the value you estimated in Part 2a (ii) greater or Less than the actual value? Explain briefly. c) The solubility product, Ks of lead iodide, PbI2, at 25°C is 7.90 x 10-9. For a saturated solution of both, PbCl2 and PbI2, the concentration of I- was Set at 4.31 x 10-4 M. Calculate the concentration of chloride in this solution?
