How does the acidified permanganate solution react with
iron (II) ions
Write the ionic equations for the reactions.

Explanation

Reactions of `KMnO_(4)` in acidic medium
`MnO_(4)^(-)+8H^(+)+5e^(-)rarr Mn^(2+)+4H_(2)O`
Iron (II) ions : Ferrous is oxidised to ferric.
`[Fe^(2+) rarr Fe^(3+)+e]xx5`
From equation (i) and (ii) `5Fe^(2+)+MnO_(4)^(-)+8H+ rarr Mn^(2)+4H_(2)O+5Fe^(3+)`
