The application of the galvanostatic potential—time technique to analysis in molten salts

Transition times of electrode processes have been determined from cathode potential-time relations at constant current, at various concentrations, current densities and temperatures, in the following molten salt solutions: PbCl 2 in LiCl-KCl; AgNO 3 in NaNO 3 ; AgNO 3 + NaCl in NaNO 3 ; AgNO 3 in NaNO 3 -KNO 3 ; AgNO 3 + KCN in NaNO 3 -KNO 3 ; Pb(NO 3 ) 2 in NaNO 3 -KNO 3 ; PbCl 2 in NaNO 3 -KNO 3 ; Cd(NO 3 ) 2 in NaNO 3 -KNO 3 . In general, S and's equation for the transition time, in the case of mass transfer by semi-infinite linear diffusion, is obeyed. Diffusion coefficients, energies of activation for the diffusion processes and solubility products are calculated. Information concerning complex formation and the structure of molten salts is reported.
