Abstract

The solubility of argon was measured at five temperatures between 5 and 25° in water and in aqueous solutions of electrolytes: LiCl (1 m), NH4Cl (1 m), NaCl (1 m), KCl (1 m), KBr (1 m), NaI (1 m), and KI (1, 2, and 4 m). The entropy and enthalpy of solution of argon were calculated from the temperature dependence of the solubility. The difference in these quantities in solution of electrolytes and in pure water is interpreted in terms of a "two-structure" model for liquid water and is attributed to the decrease of the "degree of crystallinity" of the water caused by the added electrolytes.
