Chromium (III) Sulfide is the sulfide salt of trivalent chromium.

[edit] 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.

[edit] Health effects

Chromium is a confirmed carcinogen in humans. However, because chromium (III) sulfide is fairly insoluble in water, it is much less toxic than other chromium compounds.
