`MnO_(4)^(-) + 8H^(+) + 5e to Mn^(2+) + 4H_(2)O`
`Fe^(3+) + e to Fe^(2+) , E^(@) = +1.51` V
`Cl_(2) + 2e to 2Cl^(-), E^(@) = +0.77` V
`Cl_(2) + 2e to 2Cl^(-), E^(@) =+1.36` V
`Ce^(4+) + e to Ce^(3+), E^(@) = 1.76`
Choose the incorrect statement among the following:

Options

A. `MnO_(4)^(-)` is a sufficiently strong oxidant in acidic solution (pH=0) to oxidise `Fe^(2+)` ion.
B. `Fe^(2+)` ion cannot be titrated against standard `KMnO_(4)` solution is the medium is made acidic (pH=0) by adding HCl.
C. `MnO_(4)` ion cannot oxidise `Ca^(3+)` in acidic medium (pH=0)
D. `Fe^(2+)` cannot be titrated against standard `KMnO_(4)` solution in acid medium (pH=0 in presence of `Ce^(3+)` ion.

Answer

D
