Abstract
In electrochemical studies of metal chlorides dissolved in eutectic melt it is often desired to convert the metal‐metal ion oxidation potentials Ea relative to a in eutectic reference electrode to those Eb based on the chlorine reference electrode. Such conversion can be made by using the emf Ec of the in eutectic/Cl2 cell, and involves a correction term ΔE. By using cases where both Ea and Eb can be determined independently, studies have been made of the variation of ΔE with the nature and concentration of the metal ions in the melt, the temperature of the melt, the concentration of in the reference electrode, and the nature of the membrane separating the reference and metal electrodes. This information gives an estimate of the reliability of data obtained when the two reference electrodes are interchanged.
