In the corrosion of Iron metals, Iron metals reacts with water and oxygen and forms hydrated oxide called Rust.
Addition of oxygen or removal of hydrogen is called a oxidation Reaction. It takes place only in the presence of Oxygen, water and moisture.
When a Substance, Gains oxygen or losses Hydrogen During a chemical reaction , It is oxidised.
4Fe + 3O2 + 2xH2O –» 2Fe2O3. xH2O
Since , Iron metal combines with water and Oxygen to corrode.
When Oxidation Occurs, a thin, porous, coating of reddish brown or yellow covers the metal.
It can be prevented by :-
» By Painting
» By Electroplating
» By Galvanising
» By Anodizing.
