This paper gives a study of solubilities of the K_2SO_4(NH_4)_2SO_4H_2O and KClNH_4ClH_2O threecomponent aqueous salt systems with solid solution. Pitzer thermodynamic model has been used to calculate the solubilities in systems. The activity product constant correlations are also obtained for calculating the solubilities in theory. The calculated results are in agreement with literature data. The results also showed that Pitzer equations can be used in aqueous salt system with solid solution.
