Explain corrosion class 10
WebCorrosion is the wearing away of metals due to chemical reactions, mainly oxidation. In this process, metals lose their metallic properties. This causes a lot of damage to car bodies, ships, bridges, iron railings and to all … WebRusting is a type of Chemical Change. It results in the formation of Iron Oxide which is an entirely new substance. Chemical Reaction of Rusting is as follows: Iron + Oxygen (from environment) + Water (Humidity) —> Iron Oxide (Rust) Fe + O 2 + H 2 O —> FeO and Fe 2 O 3. Iron occurs naturally in two different forms: Iron (II) and Iron (III).
