Question

name the acid that renders aluminium passive. give reason for this.​

Answer 1

Concentric nitric acid, both in diluted or concentrated form renders aluminium passive.

Explanation:

• This is because, when aluminium comes in contact with nitric acid, it forms a thin oxide coating on the surface of the metal.
• This layer of oxide formation prevents further reaction from occurring with the nitric acid.
• The chemical reaction that occurs during this process is that aluminium reacts with nitric oxide to produce aluminium nitrate, aluminium dioxide and water.  

Al + 6HNO3 -> Al(NO3)3 + 3NO2 +H2O
