Beryllium and scandium electrode potentials in fused LiCl–KCl eutectic

Abstract

Electrode potentials of the Be(II)–Be(0) and Sc(III)–Sc(0) systems were measured in dilute solutions of the ionic species in fused LiCl–KCl eutectic at 450 °C. Standard molar electrode potentials of these couples of −2.039 ± 0.013 V and −2.553 ± 0.015 V against a standard molar platinum reference were calculated. It was shown by voltammetric and chronopotentiometric methods that the equilibrium [Formula: see text] suggested by previous authors was not significant in this medium.
