Write balanced equation for the oxidation of Ferrous ions to Ferric ions by permanganate ions in acid solution. The permanganate ion forms `Mn^(2+)` ions under these conditions.

Explanation

Net ionic reaction:
`MnO_(4)^(-) + Fe^(2+) + H^(+) rarr Mn^(2+) + Fe^(3+)
Oxidation half reaction:
`Fe^(2+)+Fe^(3+)+ e^(-) ................(1)
Reduction half reaction:
`MnO_(4)^(-) + 5e^(-) rarr Mn^(2+) .................(2 )
(1)xx5 =gt 5Fe^(2+) rarr 5Fe^(3+) + cancel(5e^(-))`
(2) `=gt MnO_(4)^(-)+ cancel(5e^(-))rarrMn^(2+)`
`MnO_(4)^(-)+5Fe^(2+)rarr5Fe^(3+)+Mn^(2+)` (Add(1) and (2))
To balance O and H, `H^(+)` and `H_(2)O` are added.
`MnO_(4)^(-)+5Fe^(2+)+8H^(+)rarrMn^(2+)+5Fe^(3+)+4H_(2)O`
