On the basis fo the standard electrode potential values stated for acid solution, predict whther Ti^(4+) species may be used to oxidize Fe^(II) to Fe^(III). {:("Reaction","E/V"),(Ti^(IV)+e^(-)toTi^(3+):,+0.01),(Fe^(3+)+e^(-)toFe^(2+):,+0.77):}

Answer»

Solution :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)`.
