Ion solvation and ion association are key features of ion-solvent interactions, and their balance largely determines structure, thermodynamics, and dynamics of electrolyte solutions. Despite being studied for many years with various techniques, these effects are still intriguing because too often results obtained with different methods-each having its individual merits and limitations-cannot be connected properly due to lacking information. In this contribution, we would like to bring dielectric relaxation spectroscopy (DRS) as a further tool for solution studies to the attention of the audience. The principles of DRS and the required instrumentation are briefly introduced. The major focus will be on the kind of results obtained with this technique regarding ion solvation and association and how this information compares with results obtained from other techniques.

The authors used E.M. Kuznetsova's theory to derive an equation for computing thermal capacity of an electrolyte in a dissociated solution. This equation may also be used to determine such important characteristics as the constant and enthalpy of ion association in electrolyte solutions. This equation is derived from the simplest model, that of ion association, which allows certain solution properties to be adequately described as functions of concentration. The ion association model is based on the equilibrium between ions and ion pairs of the same kind that exists in electrolyte solutions
