Title
Calculation of Electrode Potentials for Metal Ions in KCI - LiCl Eutectic Melt by the Correspondence Principle
유재근Jae Keun Yoo, 백영현Young Hyun Paik
Abstract
A generalized treatment has been developed which determines an electrode potential in KCI-LiCl eutectic melt at higher temperatures. Entropy values for electrode reactions at 298° K could be extended to those for 723°K by using the correspondence principle. The entropy and free energy values enable one to determine electrode potentials in aqueous system at 723°K. The potentials were linearly related to experimental electrode potentials measured in the eutectic melt at the same temperature. The resulting equation becomes, E°_(exp)=0.751 E°_(cal) +0.332 where E°_(exp) and E°_(cal) stand for the experimental and theoretical electrode potentials, respectively. The potential equation was found to be applicable for the prediction of electrode potential in KCl-LiCl eutectic melt at 723°K in a reasonable accuracy.
