Question

how is iron prevent from rusting

Answer 1

Hey there !!


$\boxed{ \boxed{ \blue{ \bf \underline{Prevention \: of \: Rusting .}}}}$

1. Rusting of iron can be prevented by painting :-

→ When a coat of paint is applied to the surface of iron object then air and moisture cannot come in contact with the iron object and hence no rusting takes place.


2. Rusting can be prevented by applying grease or oil :-

→ When some grease or oil is applied to the surface of an iron object then air and moisture cannot come in contact with it and hence rusting is prevented.


3. Rusting of iron can be prevented by galvanisation :-

→ The process of depositing a thin layer of zinc metal on iron object is called galvanisation. Galvanisation is done by dipping and iron object in molten zinc metal. A thin layer of zinc metal is then formed all over the iron object. This thin layer of zinc metal on the surface of an object protect them from rusting.


4. Rusting of iron can be prevented by alloying it to make stainless steel :-

→ when iron is alloyed with chromium and nickel, then stainless steel is obtained. Stainless steel does not trust at all.


5. Rusting of iron can be prevented by tin-plating and chromium-plating.

Answer 2

Rusting can be prevented by alloying iron into steel and galvanisation.
