In 1978, Kusik and Meissner (1978) presented an equation for the prediction of activity coefficients in aqueous electrolyte solutions, based on parameter q. In this work the temperature dependency of the Kusik-Meissner parameter, q, was studied. Although the activity coefficients of electrolytes ar

โฆ Synopsis
We review the recently proposed molecular-based formalism for infinitely dilute nightemperature electrolyte solutions which establishes connections between the microscopic solvent environment around individual ionic species and their macroscopic solvation behavior. Then, we illustrate this formalism by interpreting some recent experimental results for infinitely dilute NaCl aqueous solutions. Finally, we discuss some theoretical implications, guided by the formalism, concerning the modeling of high-temperature aqueous-electrolyte solutions.

The concept of ionic hydration has been used earlier to get a new representation of the excess free energy of aqueous, single-electrolyte solutions, which leads to the prediction of y\* and # values using only two parameters for each electrolyte at 25ยฐC. Here this concept is extended to cover higher
