In Brown ring test, Fe2+ oxidizes to Fe3+, and NO3- reduces to NO.

Q. Assertion : $\ce{Fe^{+3}$ is not valid for Brown Ring Test.
Reason : Because $\ce{NO_3^{-}}$ first convert into $\ce{NO_2^{-}}$

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

In Brown ring test, $Fe X^{2 +}$ oxidizes to $Fe X^{3 +}$ , and $NO X_{3} X^{-}$ reduces to NO.
