Question

Give reason: Aluminium is a highly reactive metal, yet it is used for cooking.

Answer 1

Reactivity of Aluminum:-

1. Aluminum is a highly reactive metal, although it is corrosion-resistant.
2. Aluminum reacts with oxygen in the air to form a thin film of aluminum oxide.
3. The oxides of aluminum is extremely stable and prevent further aluminum-oxygen reactions and thus preserve the metal from getting more corroded.
4. It is also Lightweight and a good heat conductor, so it is used to make cooking utensils.

Therefore, due to the formation of aluminum oxide (${\mathrm{Al}}_2{\mathrm{O}}_3$), it is used to make cooking utensils.
