Solution
Another method for obtaining copper metal from aqueous copper(II) sulfate is through the process of electrolysis. In this method, an electric current is passed through the solution of copper(II) sulfate. This causes the copper ions to gain electrons and be reduced to copper metal at the cathode (negative electrode). The chemical reaction is as follows:
Cu2+ + 2e- → Cu
This method is often used in industry for the purification of copper.
