With carbon graphite electrodes the oxygen usually reacts with the anode to form CO 2. If copper is used for the electrodes the copper anode dissolves. The reaction is the reverse of the cathode reaction. The results of this experiment can lead to a discussion about electroplating and the electrolytic refining of copper.
