The indicator used in permanganate titration
WebSep 12, 2024 · A titrant can serve as its own indicator if its oxidized and its reduced forms differ significantly in color. For example, the intensely purple MnO − 4 ion serves as its own indicator since its reduced form, Mn 2+, is almost colorless. Other titrants require a separate indicator. The first such indicator, diphenylamine, was introduced in the 1920s.
