Used in analytical chemistry for complexometric titrations. Applied in water treatment to remove hardness. Used in pharmaceuticals cosmetics and food as a stabilizer. Common in biological and laboratory work to control metal ion concentration.

Sequesters metal ions to prevent unwanted reactions. Improves stability of formulations by binding trace metals. Helps soften water and enhances effectiveness of detergents and processes.

Ethylenediaminetetraacetic Acid Disodium Salt Solution (EDTA disodium salt) is a water-soluble chelating agent. It is the disodium salt form of EDTA usually supplied as an aqueous solution. It can bind (chelate) metal ions forming stable complexes.
