Abstract
The currently accepted theory of electrolytic solutions, as developed on the basis of coulombic interaction between ions by Huckel, Onsager, and Bjerrum, has been successful in interpreting the properties of dilute electrolytic solutions. The extension of the theory into the range of more concentrated solutions has occupied the attention of physical chemists to such an extent that there exists a tendency to neglect many other interactions that play a significant role in determining the properties of solutions of electrolytes. The most consistently neglected factor in the modern theories of solutions is the recognition of the great importance of the nature of the solvent, for which all properties but the dielectric constant are taken into little account. The importance of these non-coulombic factors in determining the properties of solutions becomes more obvious as our studies are extended to solutions of electrolytes in non-aqueous solvents.
