|(what is ?)|
Chromium(III) sulfide appears as a brownish black powder that melts at 1350 C. It is essentially insoluble in water. When heated sufficiently, it will oxidize in the presence of air or oxygen, though it is otherwise fairly stable.
Chromium (VI) is a confirmed carcinogen in humans. Because chromium(III) sulfide is fairly insoluble in water, it is much less toxic than other chromium compounds. However, in-vivo oxidation of chromium(III) to chromium(VI) can render it highly toxic and carcinogenic. As with all chromium-containing species, care must be taken to avoid ingestion of chromium(III) sulfide.
