Permanganate Oxidation of Iron(II)

MnO₄⁻ + 5Fe²⁺ + 8H⁺ → Mn²⁺ + 5Fe³⁺ + 4H₂O

Visão geral

Permanganate ion is a powerful oxidizing agent that oxidizes iron(II) to iron(III) while being reduced from Mn(VII) to Mn(II) in acidic solution. The dramatic color change from deep purple KMnO₄ to nearly colorless Mn²⁺ makes this reaction self-indicating in titrations.
