Concentrated nitric acid can be transported in vessels of iron. Why ? – InterviewSolution

1.	Concentrated nitric acid can be transported in vessels of iron. Why ?
Answer» SOLUTION :Iron METAL is passive to concentrated nitric acid. When Al vessel is FILLED with con. `HNO_3` , a PROTECTIVE OXIDE film of `Fe_2O_3` is formed. This film prevents further reactions of acid with metal. Hence `HNO_(3)` can be transported in iron cans.
