Solution: Kso=1.41-10-11 The resistance of a saturated solution of PbSO4 (very insoluble salt) at 291K is of 1.7x106 0, being the resistivity of pure water 7.1x105 Ocm. 1. Determine the solubility product of PBSO4 at 291K knowing that Am° (SO4 2)=136 0-1cm?mol 1 and Am° (Pb+2)=122 o-lcm?mol1. 2. How many centimeters will the ion move Pb+2 in one second when applying a potential difference of 25V between two electrodes 1 cm apart?
