Physical Chemistry Laboratory Experiment II-6b [Ca+2]. The true thermodynamic equilibrium constant is K s. K s = a Ca2+ a IO 3 (!) 2 (3) The "thermodynamic solubility product constant," K s, at the given T and P is constant regardless of the concentrations of ions or of the presence of other ionic or molecular species in solution.
