Caption: Electrolysis of copper sulphate solution. Electrodes (crocodiles clips) attached to copper strips (electrodes) dipped in a solution of copper sulphate (blue) and connected to a power supply (centre). The ammeter (right) shows the current being passed through the circuit. Passing an electric current through copper sulphate separates the copper from the sulphur and oxygen, with bubbles of oxygen being produced at the anode (positive electrode) and copper deposited on the cathode (negative electrode).
