Chemical properties

At 100 °C turns into _Cr2O3:

4CrO + _O2 = _2Cr2O3

It is recovered by hydrogen to metallicheskogokhrom at 1000 °C:

CrO + _H2 = Cr + _H2O

It is also possible to recover coke:

CrO + = Cr + CO Is dissolved by C in hydrochloric acid with hydrogen release and chromium chloride (III). It is not soluble in the diluted sulfuric and nitric acids
