Assertion (A) `HNO_(3)` makes iron passive. Reason (R ) `HNO_(3)` form

1.	Assertion (A) `HNO_(3)` makes iron passive. Reason (R ) `HNO_(3)` forms a protective layer of ferric nitrate on the surface of iron.A. Both Assertion and Reason are correct statements , and Reason is the correct explation of the Assertion.B. Both Assertion and Reason are correct statements , and Reason is not the correct explanation of the Assertion.C. Assertion is correct, but Reason is wrong statement.D. Assertion is wrong but Reason is correct statement.
Answer» Assertion is true, but reason is false. `HNO_(3)` makes iron passive due to formation of passive form of oxide on the surface. Hence, Fe does not dissolve in conc `HNO_(3)` solution.

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.
