摘要：

Solubility products (pK (s,MO), molality) are measured by potentiometric titration with a Pt(O-2)|ZrO2(Y2O3) oxygen electrode in the molten KBr-NaBr equimolar mixture at 973 K for the following oxides: CaO (5.00 +/- 0.3), MnO (7.85 +/- 0.3), NiO (9.72 +/- 0.04), PbO (5.20 +/- 0.3), and SrO (3.81 +/- 0.3). The correlation between pK (s,MeO) and the polarization of the corresponding cations by Goldschmidt is obtained.
