Question

Which of the following acts as an oxidising as well as reducing agent? (A)  Na2O  (B)  Na2O2  (C)  NaNO3  (D)  NaNO2

NaNO2 (sodium nitrite) act both as oxidising as well as reducing agent because in it N-atom is in +3 oxidation state (intermediate oxidation state). Oxidising property: 2NaNO2 + 2KI + 2H2SO4 → Na2SO4 + K2SO4 + 2NO + 2H2O + I2 Reducing property: H2O2 + NaNO2 → NaNO3 + H2O
