| Abstract: | The behavior of chromium(III) in molten potassium hydrogensulfate (220° C, P(H2O) = 0.04 atm) is reported. Chromium(III) exists as Cr3+ in acidic medium, and as chromium(III) sulfate, which is insoluble in neutral medium but soluble in basic medium as Cr(SO4)?2. The values of acidity constants and the solubilities of Cr(III) are reported. |
