Meaning and Definition

A type of chemical ligand, specifically an aminopolycarboxylic acid (like EDTA), that binds strongly to metal ions.

A substance that forms soluble complexes with metal ions, used in analytical chemistry, water treatment, and medicine as chelating agents. In more general contexts, sometimes used metaphorically for something that binds or complicates matters.

Common Mistakes When Using “complexone”

  • Pronouncing it as /kəmˈpleks.əʊn/ (like 'complex' + 'one'), incorrect stress.
  • Using it as a synonym for a 'complicated person' (non-technical).
  • Spelling as 'complexon' (though this variant exists, 'complexone' is standard).

FAQ

Frequently Asked Questions

No, it is a highly technical term used almost exclusively in chemistry.

No, this would be an error. The correct term for a complicated person is 'a complex person'.

Ethylenediaminetetraacetic acid, universally known by its abbreviation EDTA.

A complexone is a specific type of polydentate ligand (chelating ligand) with multiple donor atoms (like nitrogen and oxygen) that can wrap around and form very stable ring structures (chelates) with a metal ion.

Complexone is usually technical/scientific in register.

Complexone: in British English it is pronounced /ˈkɒm.plɛk.səʊn/, and in American English it is pronounced /ˈkɑːm.plɛk.soʊn/. Tap the audio buttons above to hear it.
