Question

For the reduction of NO3− ion in an aqueous solution, E° is +0.96 V. Values of E° for some metal ions are given below: V2+ (aq) + 2e− → V(s); E ° = −1.19 V

Fe3+ (aq) + 3e− → Fe(s); E° = −0.04 V

Au3+ (aq) + 3e− → Au(s); E° = +1.40 V

Hg2+ (aq) + 2e− → Hg(l); E ° = +0.86 V

The pair(s) of metal that is(are) oxidized by NO3− in aqueous solution is(are)

Options

A.V and Hg
B.Hg and Fe
C.Fe and Au
D.Fe and V

Solution

V, Fe and Hg will be oxidised by NO3−.
