chelating agent
Edetate trisodium is a salt form of ethylenediaminetetraacetic acid (EDTA), an aminopolycarboxylic acid. It is primarily used as a chelating agent to bind metal ions such as calcium and iron, forming water-soluble complexes and helping to dissolve scale or deliver iron under conditions where its oxides are insoluble.
