✦ Synopsis

The addition of silver nitrate to a caesium nitrate melt sometimes resulted in the formation of a dark-brown turbidity ; in these cases a drop of concentrated nitric acid was introduced into the melt, and the cell was evacuated to eliminate water and excess acid. Clear solutions were then obtained. ** Microscopic examination indicated the absence of any dendrite formation.

Qualitative reasoning suggested the possibility of using silver iodide as indicator electrode for silver ions in molten media. The idea has been confirmed by employing a rotating disk electrode, in which the electroactive part was a AgI-tablet, for the determination of the diffusion coefficient of s

The interdiffusion coefficient of thallous ion in molten lithium nitrate has heen measured by wave-front-shearing interferometry. The results are obtained in a region of low Tl+ concentration and can be summarized with an Arrhenius equation D = (3.95 & 1.14) x IO-' exp{-(6780 & 330)/RT}, (262-354"C)

When the solvent was lithium nitrate or a lithium-containing mixture, sodium chromate or potassium chromate was added, lithium chromate not being available. The effect on the solvent composition and on the measured association energy can be considered negligible, as generally the total alkali chroma
