jordehwa Posted March 4, 2010 Share Posted March 4, 2010 when you mix hcl and h2o2 what gas is made. Link to comment Share on other sites More sharing options...

jordehwa Posted March 5, 2010 Author Share Posted March 5, 2010 lets say if i want a solution of hcl and h2o2 to make copper chloride from elemental copper how much 30% h2o2 should i add to the hcl i think its around 30% or 35%. this is not for school its just for hobby chemistry.

DeepSpace Posted March 5, 2010 Share Posted March 5, 2010 2HCl+H2O2+Cu ----> CuCl2+2H2O 35% HCl solution : 30% H2O2 solution =1.84(approx) by weight Link to comment Share on other sites More sharing options...
Mr Skeptic Posted March 5, 2010 Share Posted March 5, 2010 The hydrogen peroxide can decompose into oxygen (regardless of the presence of HCl). Link to comment Share on other sites More sharing options...
ercdndrs Posted April 5, 2010 Share Posted April 5, 2010 Hm, maybe: 2 HCl + H2O2 -> 2 H2O + Cl2 I'm not 100% sure, so don't rely on this alone. Link to comment Share on other sites More sharing options...
Chembio Posted April 8, 2010 Share Posted April 8, 2010 I think it can be both, Cl2 gas as well as O2 gas. You have to look in to the oxidation potentials of Cl- ions and H2O2. Link to comment Share on other sites More sharing options...
