Question

Why is aluminium used for packing foods despite being highly reactive?


Please answer quickly.. my test is tomorrow

Answer 1

Answer:

we agree that aluminium is highly reactive but when aluminium reacts with oxygen then it forms a protective layer of aluminium oxide which is corrosion and rust resistant which not only protects food from being spoilt but also show acts as tin can to store food

Answer 2

Yes, it's true that aluminium is highly reactive when it is kept in air or oxygen, But still it can be used in packing foods as its upper surface is converted to aluminium oxide which is passive i.e. it is not reactive. Therefore we can use it for packing foods.
