Complexometric indicator

A complexometric indicator is an ionochromic dye that undergoes a definite color change in presence of specific metal ions.^[1] It forms a weak complex with the ions present in the solution, which has a significantly different color from the form existing outside the complex. Complexometric indicators are also known as pM indicators.^[2]
