YT2095 Posted February 12, 2008 Share Posted February 12, 2008 what grade were the H2O2 and CuSO4? I personally can`t see Any reaction mechanism that wouldn`t stabilise almost instantly to leave you copper sulphate again and some water. Link to comment Share on other sites More sharing options...
ChemSiddiqui Posted February 12, 2008 Share Posted February 12, 2008 I think YT is right, because when you look at oxidation states Cu forms then it is +2 which gives a blue ppt and Cu+1 which gives green. CU+2 being more stable. Also hydrogen peroxide is an oxidising agent so I doubt it would have any effect on CuSO4( there isn't any Cu+3 state)!

YT2095 Posted February 12, 2008 Share Posted February 12, 2008 CuO2 (the peroxide) can exist, but that`s a red color. I`m concentrating Less on the Copper ion and more on the Sulphate ion, it`s not going to convert to sulphuric acid and Not react with free copper again eventually. Maybe a Persulphate? I`m sure one of the Other guys here will know for sure though Link to comment Share on other sites More sharing options...
Psycho Posted February 13, 2008 Share Posted February 13, 2008 Couldn't it turn to H2SO4 + CuO + 1/2 O2 Link to comment Share on other sites More sharing options...
YT2095 Posted February 13, 2008 Share Posted February 13, 2008 CuO and H2SO4 reforms back to Copper sulphate again, it`s also not Green, it`s Black. Link to comment Share on other sites More sharing options...
