Why does aluminium become passive when dipped in concentrated nitric acid?
When a strip of aluminium is dipped in concentrated nitric acid, it is oxidised to aluminium oxide (Al2O3). It forms a protective coating on the surface of the metal and checks further attack by the acid. Therefore, aluminium becomes passive.
