EDTA-2Na exists in white powder, easily soluble in water, but hard to soluble in organic solvents like alcohol or ethyl ether. The PH value of 5% (25℃) water solution is 4.0-6.0. EDTA is an important complexing agent for complexing metal ions and separation of metals, the materials used for processing color photographic materials, wash bleach fixer, and dyeing auxiliaries , fiber processing agents, cosmetic additives, pharmaceuticals, food, agriculture, chemical fertilizer production, blood anticoagulant, complexing agents, detergent, stabilizer, synthetic rubber, polymerization initiator and quantitative analysis of heavy metals etc.

Application
EDTA-2Na is used in detergent,liquid soap,shampoo,agricultural chemicals,fixer solution for development of colour
film,water cleaner,PH modifier.When stating the redox reaction for the polymerization of butyl benzene rubber,it isused as part of activator for the complexation of metal ion and control of polymerization speed.
