On the basis of the standard electroe potential values stated for acid solution, predict whether, `Ti^(4+)` species may be used to oxidise `Fe^(II) " to " Fe^(III)`. Given.
`Ti^(4+) +_e^(-) to Ti^(3+),E^(ɵ)=+0.01 V,Fe^(3+)+e^(-) to Fe^(2+),E^(ɵ)=+0.77 V`

Text Solution

Verified by Experts

The `E^(ɵ)`(Standar reduction potential ) values show that `Fe^(II)` ions can be oxidised to `Fe^(III)` ions by accepting electrons from `Ti^(3+)` ion. However, the reverse reaction i.e., oxidation of `Fe^(II)` to `Fe^(III)` is not possible.
