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]. 

The determination of calcium in meat products, especially in mechanically recovered (or separated) meat (MRM/MSM), is an important estimation of the amount of bone material included in the meat. The AOAC method describes an acid digestion of the sample and reaction of an aliquot of the filtered digest with excess ethylenediaminetetraacetic acid (EDTA) under alkaline conditions to form a chelated complex with calcium ion. The excess EDTA is then titrated with calcium carbonate using hydroxynaph-thol blue as indicator. 

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...
