Question

Nitric acid can be stored in aluminium vessels but sulphuric acid cannot be. Explain.​

Answer 1

Nitric acid reacts with aluminium and forms a protective layer i.e. Al2O3. This protective layer makes aluminium unreactive towards HNO3 and therefore, it can be stored in aluminium containers.

But It says sulfuric acid cannot be stored in aluminum aluminum container because sulfuric acid dissolves aluminum metal.
