Question

What is rust? How it is formed? How can we prevent formation of rust on iron objects?

Answer 1

Answer:

Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron.

Answer 2

Answer:

To prevent rust, iron can be coated. This prevents its reaction with oxygen and water. One such process is called galvanization. This usually involves coating an iron object with a layer of zinc.
