Sacrificial Anodes are created from a metal alloy with a more negative electrochemical potential than the other metal it will be used to protect. The sacrificial anode will be consumed in place of the metal it is protecting, which is why it is referred to as a "sacrificial" anode.
                                When metal surfaces come into contact with electrolytes, they undergo an electrochemical
                                reaction known as corrosion. Corrosion is the process of returning a metal to its
                                natural state as an ore and in this process, causing the metal to disintegrate and its
                                structure to grow weak. These metal surfaces are used all around us -- from pipelines to
                                buildings to ships. It is important to ensure that these metals last as long as they can
                                and thus necessitates what is known as cathode protection.
