Question

The oxidation of iron to rust is a problem, but the oxidation of aluminum to aluminum oxide is not why?​

Answer 1

Answer:

Explanation:

When aluminum is kept in direct air,the oxygen present in air reacts and forms aluminum oxide. This oxide forms a layer over aluminum and prevents further reaction. iron mass will eventually convert entirely to rust and disintegrate. This is why the oxidation of iron rust is a problem but the oxidation of aluminum is not.

Answer 2

Answer:

When Aluminium is oxidized it form a protective layer of aluminium oxide in its surface which protects it from the further oxidation.

When iron is oxidized it rust. The rust formed do not remain attached to its surface and fall off exposing the iron for further oxidation.

Therefore, oxidation of iron to rust is a problem l, but the oxidation of aluminium to aluminium oxide is not.
