Model for Calculating the Activity Coefficients of Electrolytes in the 0 to 16 mol/L Range of Concentrations

Abstract

Based on the plasma-like theory of electrolyte solutions, areas of concentration with minimum activity coefficients are found, and the predominance of association phenomena leading to the formation of ionic associates or molecular solvates is explained. Alternative nonempirical models for estimating the activity coefficients of electrolytes are developed that produce values close to or coinciding with the available literature data in the 0 to 16 mol/L range of concentrations.
