Inclusion of solvent polarizability in the modeling of ion-dipole mixtures within the mean spherical approximation (MSA)

Abstract

The fluctuating polarization model of Høye and Stell [J. Chem. Phys. 72, 1597 (1980); J. Chem. Phys. 73, 461 (1980)] is introduced in the non-primitive mean spherical approximation (MSA) framework for an arbitrary mixture of hard spherical ions and polar polarizable solvent molecules. The thermodynamic properties are derived for this more realistic representation of an aqueous electrolyte. The obtained explicit formulas constitute a thermodynamically consistent set.
