Salts dissociate when dissolved in water:PbSO4 -> Pb2+ + SO4 2-So there are 2 different particles. 1 mol of PbSO4 produces 1 mol of Pb2+, and 1 mol of SO4 2- (one of each).Kps = [Pb2+] [SO4 2-]We will call “s” the molarity of PbSO4So the molarity of Pb2+ is also “s” (same number)And the molarity of SO4 2- is also “s” (same number)Kps = s*s = s21.82 × 10-8 = s2So, in order to find s, we have to make the square root of 1.82 × 10-8, which is: 0,00013491 M...
