Permanganate Oxidation of Iron(II)
MnO4− + 5Fe2+ + 8H+ → Mn2+ + 5Fe3+ + 4H2O
نظرة عامة
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.
