WebIn the course of this reaction, CuO is reduced to copper metal. Thus, H 2 is the reducing agent in this reaction, and CuO acts as an oxidizing agent. An important feature of … WebCathode reaction: Cu 2+ (aq) + 2e- → Cu(s) Anode reaction: 2H 2 O(l) → O 2 (g) + 4H + (aq) + 4e-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.
