We are offering our valuable customers a wide range of EDTA Salts. EDTA salt is widely used to dissolve limescale. Usefulness of EDTA salt 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 tetra sodium EDTA.
