Is there any chance that we get Cu2O directly from CuCl?

react a solution of CuCl with an aqueous solution of a soluble oxide

Cu+ has an annoying tendency to oxidize to Cu2+. i don't know if that might be trouble in the suggested reaction...

Hey would this work?

[ce]2CuCl -> 2Cu+ + 2Cl-[/ce]

[ce]Na2O -> 2Na+ + O--[/ce]

[ce]2Cu+ + O-- -> Cu2O[/ce]

Only on paper.

why would it not work?

Na2O becomes hydroxide upon contact with water.

But it still works.

CuCl + NaOH --> NaCl + CuOH

2 CuOH --> Cu2O + H2O

I don't think copper (I) hydroxide is a valid compound : /

 

"Additives such as water and acids... oxid[ize CuO] to copper(II) oxides."

 

http://en.wikipedia.org/wiki/Copper(I)_oxide

 

Thus, you'd end up with CuO from Cu(OH)2

Edit: nevermind, the same page says "Aqueous cuprous chloride solutions react with base to give [Cu2O]"

How about this reaction

 

[ce]2CuCl -> 2Cu+ + 2Cl-[/ce]

[ce]Na2CO3 ->2Na+ +CO3--[/ce]

[ce]2Cu+ + CO3-- -> Cu2CO3[/ce]

 

Now by thermal decomposition,

[ce]Cu2CO3 -> Cu2O + CO2[/ce]
