A redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution.

Redox titration is a titration in which the reaction between the analyte and titrant is an oxidation/reduction reaction. Like acid-base titrations, redox titrations normally require an indicator that clearly changes colour. In the presence of large amounts of reducing agent, the colour of the indicator is characteristic of its reduced form.
