Is disodium EDTA the same as ethylenediaminetetraacetic acid?
EDTA Na2 (ethylenediaminetetracetic acid disodium) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in many industrial and personal care products.
Why we use disodium salt of EDTA instead of EDTA?
1 Answer. The disodium salt of EDTA is preferred in hardness estimation mainly because it is more soluble in aqueous solutions which allows release of the EDTA ligand into solution to react.
