Define rusting.

Answer 1

Rusting:

• The corrosion of iron is widely known as rusting.
• When iron is exposed to moist air for a long period of time, it gets covered with a layer of a reddish-brown substance called rust.
• The reaction which shows the rusting of iron is given below:

$4\mathrm{Fe}+3{\mathrm{O}}_2+{\mathrm{xH}}_2\mathrm{O}\to 2{\mathrm{Fe}}_2{\mathrm{O}}_3.{\mathrm{xH}}_2\mathrm{O}\left(\mathrm{rust}\right)$
