where can wa find cobalt chloride?

It depends what you mean by "find". It doesn't occur as a mineral on a large scale, though it is probably present as an impurity in things like eriochalcite (copper(II) chloride). If you want to buy cobalt chloride, see the suppliers/manufacturers on the main article page. Walkerma 15:40, 28 September 2005 (UTC)

[edit] Cobalt(III) Chloride

My understanding of electrochemistry is somewhat limited, but it would seem that as the reduction potential for Co³⁺ + e^- → Co²⁺ is more positive (+1.92 V) than that for Cl₂ + 2e^- → 2Cl^- (+1.36 V), Co³⁺ would oxidize chloride to chlorine, preventing the formation of CoCl₃ and other Co³⁺ halides other than the fluoride.

Is my reasoning correct (could the compound exist, but just be unstable?) and if so, should this be noted in the article as a reason for why CoCl₃ has not been isolated? --Pyrochem 17:10, 21 July 2007 (UTC)
