Using the information given, write an expression which would give the solubility, S, as a function of the chloride ion concentration, [Cl-]. This means include all the equilibria. AgCl(s) ? AgCl(aq) So = 3.0 x 10-7 AgCl(s) ? Ag+(aq) + Cl-(aq) Ksp = 1.78 x 10-10 AgCl(aq) + Cl-(aq) ? AgCl2- (aq) K2 = 66.7 AgCl2-(aq) + Cl-(aq) ? AgCl32- K3 = 1.0
