Active cathode

Answer 2

A sacrificial anode is made up of a more active metal which is used in the sacrificial anodic protection method. (Option a)

• The process is known as Sacrificial Anode Cathodic Process (SACP).
• In this process a less noble metal is used as the sacrificial anode which is connected by the metallic conductors to the structure to be protected.
• The most common elements used for this anode includes Aluminium, Magnesium, Zinc, etc.
• their main purpose is to provide electrons to the structures to be protected and are themselves consumed.
