The anode is the electrode where oxidation occurs and electrons are lost. The cathode is where reduction takes place and electrons are gained. These reactions don't occur separately; they must work together in a reduction-oxidation reaction.For this next section, let's assume the electrodes are zinc and copper.o determine the voltage of any cell, subtract the electrode potential of the anode from that of the cathode and you get the electrode potential of the cell, or voltage. Eo cell = Eo cathode-Eo anode. Corrosion is when metal is gradually destroyed through chemical reactions, and it is a real problem in our daily lives.
Components of a corrosion cell â¢ Anode â Metal loss or corrosion occurs at the anode â¢ Cathode â Little or no corrosion occurs at the cathode â¢ Return Circuit/Metallic Path â Provides a path for electrons to flow, between the anode and cathode â¢ Electrolyte â Ionized solution capable of conducting electricity.
