Concentration changes resulting from electrolysis of 0.8 NaNO/sub 3/-0.2 AgNO/sub 3/ mixtures between silver electrodes were measured by potentiometric analysis during electrolysis (with current interruption); emf relaxation following electrolysis; chemical analysis of sections of frozen electrolyte. Enrichment in NaNO/sub 3/ at the cathode and in AgNO/sub 3/ at the anode are observed. The measurements confirm predictions from a model of component separation in mixed molten salt batteries with faradaic, migrational, and diffusional flows analogous to those in Li/LiCl-KCl/S batteries. 4 figures, 2 tables.
