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

Since `Ti^(4+) | Ti^(3+)` has lower reduction potential than `Fe^(3+)|Fe^(2+)` , it cannot be reduced in comparison with `Fe^(3+) | Fe^(2+)` ions. Hence, `Ti^(4+)` cannot oxidize `Fe^(2+)` to `Fe3^(+)`
