"concentrated HNO3 renders aluminum passive. " what is the meaning of this sentence

Answers

Answered by varadarajanshruti

Answer:

Nitric acid (dilute or conc) renders aluminium passive. Because when aluminium comes into contact with nitric acid, an impervious layer of aluminium oxide is formed. This layer of aluminium oxide will prevent the nitric acid from coming into contact with the inner aluminium metal.
