On the Statistical ``Interaction Between Ions and Molecules'' in Media of Small Dielectric Constant

In this paper the general theory of the interaction between ions and molecules in solution is discussed with particular reference to the theory of Debye on the salting-out effect. Formulae are developed for the free energy of the interaction between ions and dipoles. The formulae are applied to the dissociation equilibrium of an electrolyte in a medium of low dielectric constant.
