[edit] Precautions

The article says Avoid bringing CuCl into contact with alkynes. Why? RJFJR 15:58, 27 February 2006 (UTC)

Sorry I missed this till now. It forms a copper(I) acetylide, and such things can be very explosive. Walkerma 03:15, 11 May 2006 (UTC)

[edit] Color on Copper(I) chloride image appears wrong.

Copper(I) Chloride should, as described in the article, be white (The crystals are clear). The image however shows green crystals. I suspect this is an image of Copper(II) chloride which in fact does have green crystals. 68.208.176.4 (talk) 20:45, 27 March 2008 (UTC) MCK

It is CuCl, but as noted at copper(II) bromide, samples are usually coloured due to the presence of copper(II) impurities.

Yes, this is almost certainly due to surface oxidation. All older samples of CuCl look bright green from the CuCl₂ present. The original picture used in this article was Image:Copper(I)_chloride.jpg, one of my early efforts; that picture was taken using a freshly opened bottle of almost-new CuCl, and so the sample is lighter in colour, but the picture is not nearly as good as Ben's. If I take some more pictures, I'll see if I can get one showing a lighter colour. Walkerma (talk) 21:18, 27 March 2008 (UTC)
