WebJan 14, 2008 · Attach the positive terminal to the anode (the copper wire), and the negative terminal to the cathode (the coin). 5. Electrolyze this solution for 10 minutes or so. It seems to take a few minutes for some of the copper metal to dissolve and be available for plating. After this you can try plating some new coins. WebFeb 12, 2024 · A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O 2 → Fe 2 O 3. The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions.
