Abstract

The paloragraphic behaviour of chloride, bromide and iodide ions in several DMF-water mixtures at a temperature of 25°C is reported. The half-wave potentials change linearly to more cathodic potentials with increasing DMF content of the solvent, up to DMF-rich compositions, where deviations are observed for chloride and iodide ions. On the other hand, the Dη-product varies with solvent composition, showing a sharp maximum at water-rich compositions for the three halide ions and a smooth minimum for chloride and bromide ions at high DMF content of the solvent. These results are interpreted for different solvent mixtures in terms of the solvent structure and the ionic solvation nature of halide ions. © 1985 Springer-Verlag.
