Thallium and Tin Electrode Potentials in Fused LiCl–KCl Eutectic

Abstract

Electrode potentials of thallium and tin couples were measured in dilute solutions of the ionic species in fused LiCI-KC1 eutectic, at 450 "C. Standard molar electrode potentials of the TI(III)/TI(I) and Sn(IV)/Sn(II) couples are +O. 155 and -0.310 V against a standard molar platinum reference electrode (s.m.p.e.). The standard potentials of the TI(III)/TI(O) and Sn(IV)/Sn(O) couples were calculated to be -0.385 and -0.964 V, respectively, vs. the s.m.p.e.
