Description:
Ethylenediaminetetraacetic acid, widely abbreviated as EDTA (for other names, see Table) is a polyamino carboxylic acid and a colourless, water-soluble solid. Its conjugate base is named ethylenediaminetetraacetate. It is widely used to dissolve scale. Its usefulness arises because of its role as a hexadentate ('six-toothed') ligand and chelating agent, i.e. its ability to 'sequester' metal ions such as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA.
