How Magnesium Anodes Help Stop Corrosion Effectively?
Magnesium anodes called sacrificial anodes are protective in nature. The electrolysis process needs two electrodes, the anode and cathode and these are generally metallic in nature and thus can corrode easily on exposure to the electrolyte for a long time. Thus to prevent thus a remedy is sought and magnesium anodes are used. These find use in boats and ships to protect them from corrosion. Magnesium is very active and in fact one of the most active metals therefore gets oxidized more easily than any other metal. Actually the electrons from the anode get released and are attracted to the base metal. This acts as a cathode. This needs protection from corrosion. In a ship, a magnesium anode is connected electrically to its hull. In the presence of water and oxygen this metallic anode made of this reactive metal will start losing some of its electrons and become the magnesium cations and stay so in solution. These electrons will actually flow toward the steel hull of the ship and the diss
