Does anyone knows if Copper(II) Chloride is soluble in 1-Propanol or 2-Propanol? (Posted by 202.156.6.54, 23 March 2006).
The recent edit is not vandalism, it does rectify an error in the CAS number. I checked [www.hazard.com an MSDS] and Alfa and the 39-4 ending is correct. It appears that the Aldrich catalogue has the incorrect CAS no., that's where the error came from. Walkerma 06:13, 8 June 2006 (UTC)
"CuCl2 also behaves as a mild Lewis acid, for example in its reaction with HCl (or other chloride sources) to form the complex ions CuCl3- and CuCl42-." I want to ask if sodium choride can be used as chloride source? Superdvd 09:23, 18 January 2007 (UTC)
Thanks for your help very much. However,when I add copper(II)chloride into sodium chloride(both are dilute solution), not much observable change, just turn a bit more yellow......Is complex formation only occur in saturated solution? I am really interest in it. Superdvd 23:18, 18 January 2007 (UTC)
I was wondering whether copper II chloride reacts with hydrogen peroxide to form oxygen gas, hydrochloric acid, and copper I chloride.
2 CuCl2 + H2O2 --> 2 CuCl + 2 HCl + O2
The insoluble copper I chloride may then react with the hydrochloric acid to form a soluble hydrochloric acid-copper I chloride adduct.
CuCl + HCl --> HCuCl2
Just a thought. -- 98.221.179.18 ( talk) 22:34, 3 March 2010 (UTC)
The paragraph "Safety" states that "Copper(II)chloride can be toxic and highly flammable". Flammable? How should it be? The copper is already in its highest oxidation state. The MSDS [1] gives hazard symbols for "toxic" and "harmful to environment", but NOT flammable. I am pretty sure that the statement "flammable" is an error. (Edit: See also in the infobox: "Flash point: not flammable") -- Andi47 ( talk) 13:30, 30 November 2015 (UTC)

I'm putting the article on hold for a week until 30 August to allow time for the issues raised to be addressed. Regards, Amitchell125 ( talk) 09:37, 22 August 2023 (UTC)
Apart from one slightly questionable source in the References section, everything now looks good, so I'm passing the article. Great work, Amitchell125 ( talk) 15:59, 25 August 2023 (UTC)
