Ethylenediaminetetraacetic acid (EDTA) is a versatile chemical compound with a wide range of applications. It’s particularly known for its ability to chelate metal ions, forming stable complexes.

Structure and Properties

EDTA is a polyamine carboxylic acid that forms strong, water-soluble complexes with a variety of metal ions, including calcium, magnesium, iron, and copper. This chelating ability is due to its multiple nitrogen and oxygen donor atoms that can coordinate with metal ions.
