Correlation of the enthalpies of hydration and solution of nonelectrolytes in water with their physicochemical characteristics.

The enthalpies of hydration and solution of organic substances in water at infinite dilution cannot be quantitatively characterized using any single correlation parameter. A correlation analysis using linear multiparameter equations shows that these quantities are governed by the combined effect of the nonspecific and specific solvation and the molar volume.
