Empirical parameters of lewis acidity and basicity for aqueous binary solvent mixtures

Empirical parameters of Lewis acidity, E N T , introduced by Reichardt et al., and Lewis basicity, B KT , introduced by Kamlet and Taft, have been determined for mixtures of water with ten organic solvents. In the case of water/alcohol mixtures a distinct dependence between these acidity and basicity parameters have been found. For the other solvent mixtures the E N T on B KT dependence is more complex even if these parameters are purified from non-specific solute/solvent interactions.
