For the reduction of $$NO_{3}^{-}$$ ion in an aqueous solution, $$E^0$$ is +0.96 V. Values of $$E^0$$ for some metal ions are given below
$$V^{2+}(aq) + 2e^{-} \rightarrow V$$ $$E^0 = -1.19$$ V
$$Fe^{3+}(aq) + 3e^{-} \rightarrow Fe$$ $$E^0 = -0.04$$ V
$$Au^{3+}(aq) + 3e^{-} \rightarrow Au$$ $$E^0 = +1.40$$ V
$$Hg^{2+}(aq) + 2e^{-} \rightarrow Hg$$ $$E^0 = +0.86$$ V
The pair(s) of metals that is(are) oxidized by $$NO_{3}^{-}$$ in aqueous solution is(are)
