Stieglitz1 pointed out in 1908 that the derivation of the solubility product law based on the application of the law of mass action to strong electrolytes is objectionable. Nevertheless many elementary textbooks still give it. Washburn2 later gave a satisfactory thermodynamic derivation, and Butler3 has more recently given a satisfactory statistical one. Another thermodynamic derivation is possible using the now familiar concepts of free energy and activity.
