  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.
  Usage:used as bleaching fixer for the color sensitive materials developing and processing, and applied as dyeing and printing auxiliary, fiber treatment additives,fiber treatment additives, cosmetics additives, anticoagulant, complexing agent,also used as fertilizer industry.
