Question

Why the iron galvanized with zinc ?Can it be galvanized by with copper?If not why?

Answer 1

Bcoz zinc forms a protective coating over the surface of iron and it does not get easily corroded,oxided,etc

Answer 2

Iron is galvanized with zinc to protect it from rusting. This is because zinc is more reactive than iron. Copper is less reactive than iron therefore, iron cannot be galvanized with copper.
