Question

Name one element in which corrosion is not proved to be wasteful

Answer 1

Zink and aluminum in which corrosion not proved to be wasteful

Answer 2

Aluminium is the metal in which corrosion is not proved to be wasteful.

Explanation:

• The corrosion of elements like aluminium and copper results in the forming of a particular thin layer of oxides.

• This layer is important as it then prevents further corrosion from happening.

• These layers are not flaky or aren't easily worn off.

• The layer formed in the case of aluminium is the $Al_2O_3$layer.

• These layers are inert or non-reactive in nature.

• Therefore the corrosion in such metals is not supposed to be wasteful.
