Determine the hardness of water Of PDAM water V. Basic Theory A. Complexometry Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution. An indicator capable of producing an unambiguous color change is usually used to detect the end-point of the titration. A complex is a molecule or ion formed by the reaction of two or more ions or molecules capable of independent existence. The most important complexation reactions from an analytical point of view are those between a metal ion in solution and a complexing agent. A metal atom can usually form a bond with one or more donor atoms which have at least one unshared pair of electrons. The number of donor atoms which bond with a given atom depends on the number of electron pairs that the metal ion can accept, in other words, the coordination number of the metal ion. Complexing agents, or ligands, which can provide more than one pair of electrons (multidentate ligands), are also called chelating agents. Complexometric titrations are particularly useful for determination of a mixture of different metal ions in solution. An indicator with a marked color change is usually used to detect the end-point of the titration. In a complexometric titration, a solution containing the free metal ion of interest is titrated with a solution of chelating agent until all of the metal ions are completely complexed. The endpoint is usually measured with an indicator ligand that forms a colored complex with the free metal ion.
