Question

For the reduction of NO_3^- ion in an aqueous solution, E° is +0.96 V. Values of E° for some metal ions are given below V^ 2+ (aq) + 2e^- V E° = −1.19 V Fe^ 3+ (aq) + 3e^- Fe E° = −0.04 V Au^ 3+ (aq) + 3e^- Au E° = +1.40 V Hg^ 2+ (aq) + 2e^- Hg E° = +0.86 V The pair(s) of metals that is(are) oxidized by NO_3^- in aqueous solution is(are)
