Did you know?
Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe /Fe ) and calcium ions (Ca ), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale as well as to deliver iron ions under conditions where its oxides are insoluble.

WebApr 5, 2024 · When a di-or polydentate ligand uses its two or more donor atoms to bind the same central metal atom or ion, it is called chelation. The resulting complex has ring … WebLigands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate. Ethylenediamine is NH 2−CH 2−CH 2−NH 2 has the two donor atoms. So, it can bind with the central atom via two nitrogen atoms. So, it is a bidentate ligand.
