摘要：

The formation constants of Cu(II) and Dy(III) with N-substituted anthranilic acids have been determined potentiometrically by varying proportions of dioxane-water, acetone-water, isopropanol-water. and ethanol-water at 30 degrees C and 0.1 M ionic strength. The results are discussed with reference to the change in dielectric constant of water in the presence of organic solvent, change in structure and hydrogen bonding in water, relative solvent basicity and proton solvation by the organic solvent.
