What is the explanation for the apparent unreactivity of aluminium?

Answer 1

Aluminum does not react very well with the oxygen in the air but it is in fact quite a reactive metal. The reason it doesn't react is that it has already reacted,but the aluminum oxide has formed in a thin, tightly bonded layer that protects the aluminum foil from further attack.

Answer 2

The apparent unreactivity of aluminum is due to the formation of a thin, protective oxide layer on its surface when exposed to air. This oxide layer acts as a barrier, preventing further oxidation and corrosion of the metal. Additionally, aluminum oxide is a stable compound with high bond strength, further contributing to the metal's resistance to chemical reactions. This passive oxide layer is what makes aluminum highly corrosion-resistant in many environments.

Answer 3

Aluminium has a layer of oxide on the metal which prevents it from readily reacting or even rusting.

The following isrecommended before reacting it so as to remove the oxide layer:

a)Clean with sand paper

b) Dip in dilute solution of sodium hydroxide

Answer 4

Aluminum is unreactive because it forms a protective oxide layer on its surface when exposed to air, preventing further oxidation. This oxide layer acts as a barrier, preventing reactions with surrounding substances.

Answer 5

aluminium is highly reactive
