Question

more active metal used in sacrificial anodic protection method is known as​

Answer 1

Answer:

the materials used for sacrificial snores are either relatively pure active metals, such as zinc or magenism or aluminium alloys that have been specifically developed for use as sacrificial anodes

Answer 2

In the sacrificial anodic protection method, most pure reactive metals such as Zinc, Aluminium and Magnesium are used.

• Sacrificial anodes have to be highly active than the material it has to protect to serve the purpose.
• This sacrificial anode will protect the material from corroding by sacrificing itself.
• Zinc, Aluminium and Magnesium are prefered over other metals because of their low electrochemical potential.
• This protection method will increase the lifespan of the material ensuring safety.
• The material protected is cathode therefore it is also known as cathodic protection.
