The feasibility of the Cu/CuO electrode for O\*--ion determination and for acid-base titrations in molten KNO, at 350°C has been established. The potential of the electrode varies linearly with log [0\*-l and the slope of the calibration curve is 2.303(RT/2F) at the working temperature. This allows

The four acids NaH,PO,, Na2HPO,, NaPO3 and Na4P,.O7 were titrated potentiometricall), with NazO, in molten KNOs at 350°C. An oxygen electrode acted as indicator electrode, while a Ag/Ag(1) electode served as a suitable reference electrode. NaH2PO, neutralized in two steps, the second of which was id
