Trouble with a mixed solution of copper (II) chloride and copper sulphate.

(1/3) > >>

almannn:
I have gotten a solution of a mixture of copper chloride and copper sulphate I was hoping to recover some of the copper to use for future projects. I have tried produced copper carbonate with sodium carbonate solution in excess and filtering, however doing this still left a blue solution along with some copper carbonate.

What can be left in the blue liquid that has been filtered off? I tested the liquid with sodium carbonate and no precipitate forms... Have I missed something here?

Both copper sulphate and copper chloride reacts with sodium carbonate right?

Borek:
First of all - what is pH of the solution?

almannn:
Very basic, roughly into 11 with the indicator paper I have on hand.

almannn:
With that in mind I did add some sulphuric acid and it went clear once neutralised... Still not sure about what it could be since chemistry isn't my background.

Was the original solution clear, or murky?

If it was bluish it definitely still contained some copper. Could be you dissolved suspension and it got less visible, but the copper could not disappear.
