Answer:
Slow oxidation of iron in presence of air and moisture with formation of hydrated iron oxide is called rusting.
Iron + Oxygen → Iron Oxide → Rust hydrated iron oxide
The oxygen in the air reacts with iron and presence of moisture forms a brown coating called rust. It corrodes iron and reduces its structural strength.
