Solution

Dear Student

Corrosion of Iron in the presence of oxygen and moisture leads to formation of brown solid known as rust. This process is called rusting due to formation of rust.

4 Fe + 3 O₂ + 2x H₂O → 2 Fe₂O₃.xH₂O
This chemical reaction is oxidation reaction, as iron gets oxidised to iron (III) oxide.
