A solution to the mean spherical model for a mkture of chxged hard spheres of equal concentration and opposite ch;lrge, and hard dipoles, all of equal size, is given. The excess thermodynamic properties and the structure of the system depend on only 3 pxameters, which are the solution of a set of 3
General expressions for the Baxter factor correlation functions are obtained in the mean spherical approximation for a mixture of hard ions of arbitrary size and charge in a dipolar solvent. A method for the calculation of the total correlation functions for the model considered is proposed.
A simple electrolyte in a polar solvent is modelled by a mixture of polar hard spheres and charged hard spheres of different sizes. The model includes ion-ion, ion-dipole and dipole-dipole associations. The analytical solution of the associative mean spherical approximation (AMSA) for this model is
