Question

Aluminium is a highly reactive metal but it is used for making utensils.Why?
​

Answer 1

Answer:

Aluminium metal forms a thin layer of aluminium oxide all over its surface under the action of moist air. This layer prevents the metal underneath from further corrosion. It is cheap, easily available, malleable and ductile. Therefore, it is used to make utensils cooking.

Answer 2

Answer:

Aluminium is a highly reactive metal. It does not rust. Because it combines with oxygen and forms Aluminium oxide. The protective oxide layer prevents the metal from further oxidation and Aluminium is a light, good conductor of heat. Hence this is used to make utensils for cooking.
