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

We want to check the spontaneity of the reaction: `Ti^(4+)+Fe^(2+)toTi^(3+)+Fe^(3+)`
E.M.F. of this reaction `=+0.01+(-0.77)=-0.76V`
As EMF is -ve, the reaction is non-spontaneous, i.e., `Ti^(4+)` cannot be used to oxidize `Fe^(II)` to `Fe^(III)`.
