When an iron (II) salt is titrated with potassium permanganate, no external indicator is needed. Potassium permanganate (KMnO_4) acts as its own indicator (a self-indicator). Potassium permanganate solution is intensely purple. During the titration, it is reduced to nearly colorless Mn^2+ ions. Once all the iron (II) ions have reacted, the first drop of excess potassium permanganate solution will cause the solution to turn a persistent pale pink color, indicating the endpoint of the titration.
