Determination of a Linear Rule between the Osmotic Coefficients on Mole Fraction Base and Several Different Concentration Expressions in Single Electrolyte Solutions

In the paper, a linear rule between osmotic coefficients on mole fraction base and each of several concentration expressions is presented, respectively, in single electrolyte solutions containing various valence inorganic acids, alkalies, and salts, such as uniuni-, biuni-, triuni-, tetrauni-, bibi-, and tribi-valence inorganic acids, alkalies, and salts. A thermodynamic model based on the rule…

Presentation of a Model Describing the Osmotic Coefficients and the Activities of Water for Electrolyte Solutions

This work presents a model for thermodynamic properties of the uni-univalent electrolytic solutions based on a linear relation between a dimensionless-thermodynamic potential constructed for solvent and a newly defined probability-distribution function of water molecules around the hydrated central ion. The model allows quantitative reproduction of the osmotic coefficients for the uni-univalent electrolytic solutions, especially some…
