Answer 1

Which of the following process to be carried out to avoid the

formation of greenish layer on brass vessels due to corrosion?

a) plating b) anodization c) tinning d) alloying is alloying

Answer 2

The correct answer should be (B)- anodization.

This is explained as follows:

Brass vessels when exposed to air or water in the atmosphere, they react with them to form a compound that results in the formation of the greenish layer on the vessels due to corrosion.

To avoid this, i.e. to make the brass vessels corrosion-resistant, anodization is done.

Anodization is an electrochemical process which is done by placing the metal in an acid electrolyte bath and then passing electric current through the electrolyte.

This makes the vessel durable and corrosion-resistant.
