EDTA

Ethylenediaminetetraacetic acid; a crystalline acid that acts as a strong chelating agent and that forms a sodium salt used as an antidote for metal poisoning and as an anticoagulant.

Substance has low toxicity by ingestion. Large amounts may cause gastric upset due to osmotic imbalance through the sequestering of metal ions.

A polyamino carboxylic acid (complexone) is a compound containing one or more nitrogen atoms connected through carbon atoms to one or more carboxyl groups. Polyamino carboxylates, which have lost acidic protons, form strong complexes with metal ions by donation of electron pairs from the nitrogen and oxygen atoms to the metal ion to form multiple chelate rings.
