Question

Is rusting of iron an example of a chemical reaction? If yes, give the chemical equation for rusting of iron.

Answer 1

Yes, rusting of iron is a chemical reaction. When iron rusts, it reacts with oxygen present in water or moisture in the air to create a new compound called hydrated iron (lll) oxide.

$\mathrm{Fe}\left(s\right)+O_2\left(g\right)🡪{\mathrm{Fe}}_2{O}_3.{\mathrm{xH}}_{2}O\left(s\right)$

$F{e}_2{O}_3.x{H}_{2}O$ is commonly known as rust and has properties entirely different from that of iron or oxygen.
