Ethylenediaminetetraacetic acid - Wikipedia

Ethylenediaminetetraacetic ,acid, (EDTA) is an aminopolycarboxylic ,acid, with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate ("six-toothed") chelating agent.EDTA is produced as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA.
