What is Chromium(III) chloride?
[[File:Chromium(III) chloride green hexahydrate.jpg|thumb|Green hydrated chromium(III) chloride]] [[File:Chromium(III)-chloride-purple-anhydrous.jpg|thumb|Purple anhydrous chromium(III) chloride]] '''Chromium(III) chloride''' is a [[chemical compound]] composed of chromium in its +3 [[oxidation state]] and [[chloride]] [[ion]]s. It is green when hydrated (attached to water molecules) and purple when anhydrous (not attached to water molecules). It can be formed by dissolving [[chromium]] in [[hydrochloric acid]] or by dissolving [[chromium(III) oxide]] in [[hydrochloric acid]]. Chromium in its +3 oxidation state is much less toxic than chromium in its +6 oxidation state, such as [[chromate]]s. ==Related pages== *[[Chromium(III) oxide]] *[[Chromate]]s *[[Chromium]] {{chem-stub}} [[Category:Chlorine compounds]] [[Category:Chromium compounds]]
