Contents
Preparation
It may be formed by the reaction of hydrogen sulfide with chromium(III) oxide or other chromium salts.
Properties
Chromium(III) sulfide appears as a brownish black powder that melts at 1350 C. It is essentially insoluble in water.[1] When heated sufficiently, it will oxidize in the presence of air or oxygen, though it is otherwise fairly stable.
Health effects
Chromium is not a confirmed carcinogen in humans. However, because chromium(III) sulfide is fairly insoluble in water, it is much less toxic than other chromium compounds.
