Question

to prevent rusting ,a layer of .......... metal is applied on iron sheets

Answer 1

Metal starts getting rusted due to regular exposure to air.
In order to prevent rusting, a layer of zinc is always applied on iron sheets.

As zinc starts rusting earlier in comparison to iron, a layer of zinc is applied to prevent further rusting.

This method is called galvanization.

Answer 2

Answer:

The answer is zinc metal.

Explanation:

• To prevent rusting, a layer of zinc metal exist applied to iron sheets.
• Zinc exists as a non-corrosive metal. Therefore, a layer of zinc averts rusting.
• Zinc exists applied to steel, which serves as a sacrificial anode and controls rusting. This procedure of applying zinc is called Galvanization.
• Galvanization or galvanizing is the process of applying a protecting zinc layer to steel or iron, to control rust. The most standard approach is hot-dip galvanizing, in which the regions are submerged in a bath of hot, molten zinc
