WebEthylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2.This white, water-insoluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale as well as to deliver iron ions … WebThe buffer region extends over the approximate range pKa ± 2, though buffering is weak outside the range pKa ± 1. In water, measurable pKa values range from about ?2 for a strong acid to about 12 for a very weak acid (or strong base).
