Abstract

The dissociation of CO 2−3 (pK = 2.4 ± 0.2) and precipitation of MgO (pL MgO = 10.66 ± 0.1) in a KBr melt at 800°C were studied potentiometrically with the use of a Pt(O2)|ZrO2|(Y2O3) membrane oxygen electrode. The direct calibration of the electrochemical circuit allowed only the equilibrium concentration of O2− (of strong bases) to be determined in the melt. The total concentration of oxygen-containing impurities, including CO 2−3 and CO 2−4 weak bases, can be found by the potentiometric titration of a sample of KBr by adding MgCl2 (Mg2+), a strong Lux-Flood acid, which causes the decomposition of these oxygen-containing anions. This reaction can also be used to remove oxo anions from alkali metal halide melts.
