Answer» For the reduction of $N O_{3}^{-}$ ion in an aqueous solution, $E^{o}$ is $+ 0.96 V$ . Values of $E^{o}$ for some metal ions are given below. $V^{2 +} (aq) + 2 e^{-} \to V E^{0} = - 1.19 V$ $F e^{3 +} (aq) + 3 e^{-} \to F e E^{0} = - 0.04 V$ $A u^{3 +} (aq) + 3 e^{-} \to A u E^{0} = + 1.40 V$ $H g^{2 +} (aq) + 2 e^{-} \to H g E^{0} = + 0.86 V$ The pair(s) of metals that is (are) oxidised by $N O_{3}^{-}$ in aqueous solution is (are)
