Question

A student made a list of the applications of electroplating on metals. He learns that zinc metal is electroplated over iron. Why the electroplating of iron is done?​

Answer 1

Answer:

The electroplating of iron is done to make it resistant to atmospheric moisture. ... Iron metal is coated with a layer of zinc and this process is termed as galvanization. Since zinc is more reactive than iron, it will protect the surface of iron from atmospheric moisture and thus prevent corrosion
