A '''complexometric indicator''' is an [[ionochromism|ionochromic]] [[dye]] that undergoes a definite color change in presence of specific metal [[ion]]s. It forms a weak [[complex (chemistry)|complex]] with the ions present in the solution, which has significantly different color than the form existing outside of the complex.

Line 32 ⟶ 31:

* [[Calmagite]]

* [[2-Cresolphthalexon]]

In some settings, when the titrated system is a redox system whose equilibrium is influenced by the removal of the metal ions, a [[redox indicator]] can function as a complexometric indicator.
