Description
|
it is a polyamino carboxylic acid and a colourless, water-soluble solid.
Its conjugate base is named ethylenediaminetetraacetate.
It is widely used to dissolve limescale.
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.
