ABSTRACT
The structure of an electrolyte solution, to a great extent, is formed by solvation processes that are described by various thermodynamic relations engaging proofs obtained from all kinds of radiophysical measuring methods. Theoretical calculation methods of thermodynamic functions of ion solvation can be broken down into two groups. The first group involves calculations where a solvent is considered as a continuous dielectric. Historically, these calculations were the first attempts to understand and to calculate the ion solvation process. These works belong to Born [1], Webb [2,3], Grahame [4], Hasted et al. [5], Frank [6], Hush [7], and others. In this chapter, we do not take into account works in which division methods of thermodynamic functions of electrolyte solvation into ionic components are analyzed.
