Redox Titration
A titration in which the reaction between titrant and analyte involves electron transfer.

In depth
The end point may be shown by a self-indicating titrant, by a specific indicator such as starch, or by a redox indicator that changes colour at a characteristic potential. Many redox titrations require careful pH control, since the oxidising power of the reagent depends on it.
Examples in the real world
Titrating iron(II) with potassium permanganate, whose first excess drop turns the solution permanent pink.
