✦ Synopsis

have been used to determine activity coeffcients of Na,O in molten NaCl, Na,SO,, and Na,CO,. Extreme negative deviations from Raoult's law were observed (y -z 10e3). In NaCl and Na,SO,, y is independent of concentration below 1 m/o Na,O, but in Na,CO,, the activity is nearly independent of concentration, probably because the oxide reacts with dissolved 0, to form superoxide (0;).
