Anode reaction: Cu(s) → Cu 2+ (aq) + 2e-At the cathode: A deposit of copper forms on the cathode. Cathode reaction: Cu 2+ (aq) + 2e-→ Cu(s) During this electrolysis, the mass gained of copper at the cathode is equal to the mass lost at the anode. chip by statehttp://chemed.chem.purdue.edu/demos/main_pages/20.2.html grant heating systems

"WebAt the anode, hydrogen is oxidized according to the reaction: producing water and releasing electrons. The electrons flow through an external circuit and return to the cathode, reducing oxygen in the reaction: producing hydroxide ions. The net reaction consumes one oxygen molecule and two hydrogen molecules in the production of two water molecules. " - Ionic equation for oxygen at anode
