Question

Iron on exposure to moist air forms rust. It is a flaky substance which falls off,
exposing the inner layers. Aluminium on the other hand forms a protective layer
of its oxide on exposure to moist air. Should this oxidation of aluminium be
considered a problem and prevented? Explain.​

Answer 1

Answer:

no this is not a problem for the substance like alumimium

Explanation:

it is so because the aluminum oxide only froms on the outer layer of the metal this protects the inner layer from getting corodded

where as in iron the rust in upper layer slowly spreads in the inner layers of the metal causing it to corrode

please follo.w me and mark this answer as brainliest I hope this answer helped you

Answer 2

Answer:

Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide.

Explanation:

Aluminium when exposed to air ,a layer of aluminium oxide is formed on surface of aluminium metal which prevents it from further corrosion
