The expression for the activity coefficients of electrolytes in solution based on the three-dimensional facecentered-cubic array1 can be used to find an expression for the relative partial molar enthalpies and the heats of dilution. Analysis of tabulated data shows excellent agreement with predicted results up to concentrations of about 1 M. This is further evidence that an analysis of the forces and energies between ions immersed in a dielectric medium must include the dielectric gradient effects as well as the classical coulombic effects.In a previous paper, 1 1: 1 electrolytes in solution in water were shown to assume a loose face-centeredcubic lattice. An analysis of the forces and energies acting between these structured ions, based on Coulomb’s law and the field-dielectric-gradient effect, re-sulted in an expression for the electrical free energies (activity coefficients) that was a simple function of the concentration. The application of classical thermodynamics to the free energy expression should allow the determination of relative partial molar enthalpies or of heats of dilution. This paper shows the results of such an application.
