Ethylenediamine tetraacetate ion denticity

Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe /Fe ) and calcium ions (Ca ), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale … See more Textile industry In industry, EDTA is mainly used to sequester (bind or confine) metal ions in aqueous solution.
