Chelation (/ kiːˈleɪʃən /) is a type of bonding and sequestration of metal atoms. It involves two or more separate dative covalent bonds between a ligand and a single metal atom, thereby …

Nov 15, 2025 · A chelating agent is a substance that forms a stable, complex structure with a metal ion. The term is derived from the Greek word chele, meaning “claw,” which illustrates …

Jun 24, 2023 · A chelating agent is a chemical whose molecules have the ability to create many bonds with a single metal ion. In other words, a chelating agent is a multidentate ligand.

Aug 19, 2025 · A chelating agent is a chemical compound capable of forming multiple bonds with a single metal ion, much like a crab’s claw grasps an object. These agents effectively “trap” or …

The word chelating, derived from the Greek chele, “claw,” describes the pincer-like way in which such a ligand can grab a metal ion. A chelating agent which forms several bonds to a metal …

Chelating agents are a class of chemicals that have the ability to chelate metal ions. The chelating agent, like a crab’s “chela” , clamps down on the metal ion, and the chelating agent and the …

Chelating agents control metal ions by blocking the reactive sites of the metal ion and preventing them from entering into their normal (and in many cases undesirable) reactions.

Jul 2, 2025 · A chelating agent, therefore, is a molecule engineered or naturally occurring to bind strongly to a metal ion, typically a transition metal or lanthanide/actinide.

Dec 26, 2025 · In medical practice, chelating agents, particularly salts of EDTA, or edetic (ethylenediaminetetraacetic) acid, are widely used for direct treatment of metal poisoning …

Chelating agents yielding soluble metal complexes are also called sequestering agents. 1 A chelating agent has at least two functional groups which donate a pair of electrons to the …
