A common reagent used in complexometric titrations is ethylenediaminetetraacetic acid (EDTA). It is often used to determine the concentration of metal ions present in a solution. 

EDTA (ethylenediaminetetraacetic acid) (H02CCH2)2NCH2CH2N-(CH2C02H)2, the most widely used reagent for complexometric titrations. It forms 1 1 complexes with virtually all cations with a charge of 2 or more, effective formation constant Equilibrium constant for formation of a complex under a particular stated set of conditions, such as pH, ionic strength, and concentration of auxiliary complexing species. Also called conditional formation constant. 

The solubility of the complex anion Ag(CN)2 in contrast to the high insolubility of neutral silver cyanide (AgCN) was exploited for the determination of silver (and/or cyanide) by Justus von Liebig as long ago as 1851 this procedure may well be cited as the best established complexometric titration preceding the great developments brought about by G. Schwarzenbach in 1940 when he pioneered the use of ethylenediaminetetraacetic acid, EDTA, and other aminopolycarboxylic acids as titrants" and opened up new vistas in titrimetry (see Section 10.6). 

Ethylenediaminetetraacetic acid can be used as a reagent for the titration of Ti(lV). However, the reaction proceeds slowly, and the Ti(IV) species tend to hydrolyze during the titration, so that a back-titration method is necessary to make the complexometric method work properly [26]. 

EDTA (ethylenediaminetetraacetic acid) (H02CCH2)2NCH2CH2N-(CH2C02H)2, the most widely used reagent for complexometric titrations. It forms 1 1 complexes with virtually all cations with a charge of 2 or more. 

Titrimetric methods based on the reaction of metal ions with a coordinating species (ligand) are more than 100 years old. If the ligand is attached to the metal by more than one functional group, it is said to be polyden-tate and the compound produced is called a chelate. The complexometric reagent that is easily the most widely used for the titration of unknown concentrations of metal ion is the hexadentate ligand ethylenediaminetetraacetic acid (EDTA), first recognized by Schwarzenbach in 1945. The structure of the molecule is...
