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 O-3 in NaCl, LiClO4, NaClO4, Mg(ClO4)(2), Na2SO4, CdSO4, K2HPO4, and Al-2(SO4)(3) salt solutions were investigated at 25 degrees C, and the corresponding K-S of these systems were determined.
