ELECTROLYTES IN BINARY SOLVENTS - AN EXPERIMENTAL APPROACH

The lack of an adequate theory to describe the properties of electroly tic solutions in binary mixed solvents makes research on such systems important. This article collates the standard enthalpies of salt solut ions in water-organic solvents with the properties of solvent componen t mixtures. in order to discuss the effect of ions on solvent structur e. Plots of DELTAH(s)0 for electrolytes with and without organic ions are compared in several groups of mixed solvents. The DELTAH(s)0 maxim a for organic ions are described by means of hydrophobic effects param eters of organic co-solvents. The role of hydrophobic interactions is shown by the comparison.
