sp(CaSO4) = [Ca 2+][SO 4 2-] = 2.4∙10-5 eq. 1 In words, this equilibrium expression implies that the product of the calcium ion concentration and the sulfate ion concentration can be no larger than 2.4∙10-5 in any aqueous solution. Saturated solutions Any aqueous solution in which the product of the calcium ion concentration and the
