The relative permittivity is a measure of the solvent’s ability to insulate opposite charges from each other and has a very significant effect on the strength of the interactions between ions especially in dilute solution. I describe the relative permittivities, εr(sln) of nonaqueous mixtures as a function of the composition at 25 ºC. Experimental data were fitted with the Redlich-Kister equation. I explained the deviation from the ideal solution in terms of the magnitude of the coefficient a0. a0 is a dominant factor governing the Redlich-Kister equation. The decrease in a0 made a plot of εr(sln) vs. x2 close to a straight line, which corresponded to the ideal solution. The cohesive forces between dissimilar components resulted in the increased effective dipole moment and, consequently, in the small negative value of a0.
