Electrode potentials of indium and gallium couples have been measured in dilute solutions of the ionic species in fused LiCl–KCl eutectic at 450 °C. Standard molar electrode potentials of the observed couples are −1.210, −0.944, and −1.136 V against a standard molar platinum reference for the In(I)–In(0), In(III)–In(I), and Ga(III)–Ga(0) couples, respectively. These oxidation states and potentials are compared with previous work in this and other fused salt systems.

Electrode potentials of thallium and tin couples were measured in dilute solutions of the ionic species in fused LiCl–KCl eutectic, at 450 °C. Standard molar electrode potentials of the Tl(III)/Tl(I) and Sn(IV)/Sn(II) couples are +0.155 and −0.310 V against a standard molar platinum reference electrode (s.m.p.e.). The standard potentials of the Tl(III)/Tl(0) and Sn(IV)/Sn(0) couples were calculated to be −0.385 and −0.964 V, respectively, vs. the s.m.p.e.

Electrode potentials of the Ru(III)/Ru(0) and As(III)/As(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 −0.107 ± 0.007 V and −0.460 ± 0.017 V against a standard molar platinum electrode were calculated. The As(V)/As(III) potential was found to be beyond the potential range of the melt.

The interdiffusion coefficient has been measured over the whole range of compositions in the NaNO3 -AgNO3 and NaNO3 - RbNO3 molten salt mixtures, using an improved version of the gravimetric interdiffusion technique. At 340 °C the interdiffusion coefficient is about 2.3 × 10-5 cm2 s-1 in mixtures with a high NaNO3 content. It increases slightly with increasing AgNO3 content and decreases with increasing RbNOs content. Good agreement is found with data obtained with other methods. There is evidence that the interdiffusion coefficient is inversely proportional to the cation radii in the melt. Interionic friction coefficients are calculated. Only three ionic species are present in dilute solutions of AgNO3 and RbNO3 in NaNO3 but there is evidence of “complex ion formation” in dilute solutions of NaNO3 in AgNO3 and in RbNO3.

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.

The standard electrode potentials for the formation of the pure solid and molten compounds Li2ZrCl6, Li2HfCl6, Na2ZrCl6, Na2HfCl6, K2ZrCl6, K2HfCl6, Cs2ZrCl6, and Cs2HfCl6 have been calculated from measured vapour pressures corresponding to their thermal decomposition at equilibrium and from available thermochemical data. Reversible potentials for the formation of Na2ZrCl6 and of K2ZrCl6 in solution according to the reaction[Formula: see text]where A is Na or K, have been calculated from available equilibrium vapour pressures as functions of the mole fractions of the alkali hexachlorocompounds. Standard potentials for the above reaction and "formal" potentials are also given. The latter are useful in predicting the electrochemical behaviour of dilute solutions of the hexachlorozirconates in alkali metal chlorides.
