Answer 2

ANSWER:-

1. Corrosion is basically and electrochemical phenomenon.The rusting of iron ,the tarnishing of silver,development of green coating on Copper and brass are some example of corrosion .
2. Use of zinc coating protect iron is called galvanization.In galvanizing iron, zinc being more reactive than iron service as an anode and is oxidize .
3. Here it is important to know that iron does not rust even after zinc coating is broken which is not true in case of thin coating over iron .
4. Therefore,Zinc is used to protect corrosion of iron.
