Ethylenediaminetetraaceticacid EDTA

Complex forming reactions find a wide utility in chemical analysis and ha c been used in titrimetric procedures for many years. Recently most attention has been concentrated on the use of ethylenediaminetetraaceticacid (EDTA) and consideration of this reagent in some detail is important. This study will also be useful in that it illustrates nearly all aspects of the use of inorganic and organic complexing agents in titrimetry.

EthylenediaminetetraaceticAcid. Ethylenediaminetetraacetic acid (EDTAH has six potential donor groups two nitrogen atoms and four carboxylate groups. If EDTA 4— acts as a hexadentate ligand to a metal, the resulting complex contains five five-membered chelate rings and has a charge that is four less than that of the metal ion.
