Question

Assertion :Nitrite can be oxidized or reduced, with the product somewhat dependent on the oxidizing/reducing agent and its strength. Reason: Nitrogen is present in some intermediate oxidation state i.e.,between its highest and lowest oxidation state in nitrite ion.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion:

Nitrite ion can be oxidised or reduced depending on oxidising/ reducing agents strength.

Example:

Oxidised:- $5N{O}_2^{-}+2Mn{O}_4^{-}+6H^{\oplus }\to 5N{O}_3^{\ominus }+2Mn{O}^{+2}+3H_{2}O$

Reduced:- $6I^{-}+2N{O}_2{}^{-}+8H^{+}\to 3I_2+N_2+4H_{2}O$

Reason:

$N{O}_2^{\ominus }$ oxidisation state +3 between 0(minimum ) and (+5) maximum oxidisation state of $N$.

Hence can be both reduced and oxidised.
