Emmasham Posted April 1, 2010 Share Posted April 1, 2010 Is there any chance that we get Cu2O directly from CuCl? Link to comment Share on other sites More sharing options...

hermanntrude Posted June 6, 2010 Share Posted June 6, 2010 Cu+ has an annoying tendency to oxidize to Cu2+. i don't know if that might be trouble in the suggested reaction... Link to comment Share on other sites More sharing options...
Bobba fett Posted June 7, 2010 Share Posted June 7, 2010 (edited) Hey would this work? [ce]2CuCl -> 2Cu+ + 2Cl-[/ce] [ce]Na2O -> 2Na+ + O--[/ce] [ce]2Cu+ + O-- -> Cu2O[/ce] Edited June 7, 2010 by Bobba fett Link to comment Share on other sites More sharing options...

Bobba fett Posted June 7, 2010 Share Posted June 7, 2010 why would it not work? Link to comment Share on other sites More sharing options...
dttom Posted June 7, 2010 Share Posted June 7, 2010 Na2O becomes hydroxide upon contact with water. Link to comment Share on other sites More sharing options...
John Cuthber Posted June 7, 2010 Share Posted June 7, 2010 But it still works. CuCl + NaOH --> NaCl + CuOH 2 CuOH --> Cu2O + H2O Link to comment Share on other sites More sharing options...
ercdndrs Posted June 7, 2010 Share Posted June 7, 2010 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 Merged post follows: Consecutive posts mergedEdit: nevermind, the same page says "Aqueous cuprous chloride solutions react with base to give [Cu2O]" Link to comment Share on other sites More sharing options...
Bobba fett Posted June 8, 2010 Share Posted June 8, 2010 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] Link to comment Share on other sites More sharing options...
