| Abstract: | Selected microscopic properties, namely ET(30) polarity, Kamlet-Taft solvatochromic parameters and dissociation constant of picric acid, have been correlated with solvent composition in 2-methoxyethanol/1,2-ethanediol mixtures. Theoretical and semi-empirical equations which embody preferential solvation of the solute and show standard deviations lower than 0.01 for solvatochromic parameters and 0.03 for pK values have been proposed. |
