why is a layer of zinc coated over iron
Anonymous:
To prevent the rusting of the iron
Iron rusts when it comes in contact with oxygen and water
so that it won't rust
yeah
it happens more in places near coast because of more amount of moisture present over there

A layer of zinc is coated over iron articles so as to protect it from rusting.When Zinc reacts with atmospheric oxygen it develops a layer of zinc oxide.This zinc oxide protects the layer of zinc as well as the iron object from corrosion.

HI !
Iron (Fe) when comes in contact with air and moisture, gets covered with a brown flaky substance called rust. This process is called rusting. It makes iron lose its hardness and destroys it. Hence,to prevent rusting,a layer of zinc is coated over iron , as a barrier , which prevents iron from coming in contact with moisture and air. Applying a coat of zinc over iron is called galvanization.
