Development and Validation of the Successor to the Weisenberger–Schumpe Solubility Model of Gas in Aqueous Electrolytes: Solubilities of Ar, He, Xe, and O3 in Electrolyte Solutions at 25 °C

A new expression for the Weisenberger–Schumpe gas solubility model in electrolyte solutions is proposed. Novel and previously published experimental data are analyzed to develop a model that allows for more accurate KS (Sechenov constants) calculations than the state-of-the-art Weisenberger–Schumpe model and suggests that the effect of dissolving gas type on KS depends on the magnitude of this constant. The concentration dependences of the Henry’s constants for Ar, He, Xe, and O3 in NaCl, LiClO4, NaClO4, Mg­(ClO4)2, Na2SO4, CdSO4, K2HPO4, and Al2(SO4)3 salt solutions were investigated at 25 °C, and the corresponding KS of these systems were determined.
