A titrant can serve as its own indicator if its oxidized and its reduced forms differ significantly in color, which initially limited redox titrations to a few titrants. Other titrants require a separate indicator. The first such indicator, diphenylamine, was introduced in the 1920s. Other redox indicators soon followed increasing the applicability of redox titrimetry.
