electrolysis copper sulfate solution with copper carbon

The products of electrolysing copper sulfate solution with copper electrodes are copper metal and copper ions (because the copper anode dissolves). Using the simple apparatus (right diagram) and two copper electrodes the products of the electrolysis of copper sulfate solution are (i) a copper deposit on the negative cathode electrode and (ii) copper dissolves at the positive anode electrode.
