Of correlation methods for solubility in ternary systems, the method of expansion of relative activity coefficients and the hydration analysis are based on the thermodynamic condition of phase equilibria. Both of them require only reliable solubility data in the ternary system and corresponding binary systems. Correlation parameters of both of these methods are interrelated and the methods are compared on the system K2SO4-H2SO4-H2O at 50 °C.
