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 K S (Sechenov constants) calculations than the state-of-the-art Weisenberger–Schumpe model and suggests that the effect of dissolving gas type on K S 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 K S of these systems were determined.
