The solubility of metallic Na in NaOH--NaBr--NaI was measured and its mechanism is discussed in two aspects; one in the chemical dissolution according to the reaction Na + NaOH yields Na/sub 2/O + 1/2H/sub 2/, or the metallic Na that electrodeposited reacts with caustic soda to become sodium oxide; and another in the physical dissolution, which is considered to be influenced by the interfacial tension between the electrolyte and the metallic Na. As the surface tension of metallic Na becomes low, the interfacial tension between electrolytic bath and metallic Na decreases, and thereby metallic Na tends to disperse. The physical solubility was found to increase with higher temperature. Chemical solubility was found to increase violently from 280 deg C, and the solubility could not be measured at low temperature for its slow reaction velocity. (P.C.H.)
