EDTA disodium salt is a salt form of ethylenediaminetetraacetic acid (EDTA), an aminopolycarboxylic acid that binds strongly to metal ions such as iron and calcium, forming water-soluble complexes. It is commonly used as a chelating agent in food and industrial applications to control metal ion reactivity and prevent scale formation.
