Complexometric titrations (also known as chelatometry) are used mainly to

determine metal ions by use of complex-forming reactions. It is a form of volumetric

analysis in which the formation of a colored complex is used to indicate the endpoint of

a titration. In this method, a simple ion is transformed into a complex ion and the

equivalence point is determined using metal indicators or electrometrically. An

indicator capable of producing an unambiguous color change is usually used to detect

the endpoint of the titration. The versatility, sensitivity, and general convenience of

complexometric titrations are dependent on the correct choice of indicators endpoint

detection.
