Nitric acid is a strong reducing agent , aluminum forms a thick layer of oxide on it while reacting with air and further nitric acid cannot oxidise Al oxide ans so nitric acid can be stored safely in it.
we can store nitric acid in aluminium containers as there is formation of thin oxide coating on the surface of the metal which prevents it from further reaction
A layer of insoluble aluminium oxide is formed on the surface.
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
This salt is aluminium nitrate.
nitric acid is light sensitve , it decomposes when expose in light. when aluminium is added to the conc HNO3 it remain passive in conc nitric acid,...... and moreover aluminium oxide layer is also form due to which it remain passive in conc nitric acid...
nitric acid
The chemical name of HNO3 is nitric acid
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)

Because when aluminium comes into contact with nitric acid, an impervious layer ofaluminium oxide is formed. This layer of aluminium oxide will prevent the nitric acid from coming into contact with the inner aluminium metal. Thus this layer protect and prevent further reaction.
Pouring concentrated Nitric acid(HNO3). It will dissolve Silver but not Aluminium because, Aluminium will form a passivation layer which is resistant to Nitric acid
Answer plc urgent
i do not know. better refer wikipedia. sorry for the inconvenience.
Aluminium is passive towards Nitric acid because Nitric acid forms a protective thin film on surface of Aluminium which protects from further reaction.
Aluminium is amphoteric which means that it displays some of the properties of both acids and bases, it will react with some bases, such as Sodium Hydroxide and also with some Acids such as concentrated Nitric Acid
