Text Solution

Verified by Experts

The correct Answer is:
b,c,d
`NO_(3)^(c-)+e^(-) rarr ?, E^(c-)._(red)=0.96V`
Compare the standard reduction potential of the given metals with that of `NO_(3)^(c-)` reduction.
`E^(c-)._(reduction)` for `NO_(3)^(c-)` is greater than `E^(c-)._(reduction)` of `(i),(ii),` and `(iv).`
So, `NO_(3)^(c-)` will be able to oxidize `Fe, Hg` and `V.`
So pairs are as in `(b),(c),` and `(d)`.
