The equilibrium constant for the following reaction is 1.0 × 10 23 : Cr 3+ ( a q ) + H 2 E D T A 2 − ( a q ) ⇌ C r E D T A − ( a q ) + 2 H + ( a q ) EDTA is used as a complexing agent in chemical analysis. Solutions of EDTA, usually containing the disodium salt Na 2 H 2 EDTA, are used to treat heavy metal poisoning. Calculate [Cr 3+ ] at equilibrium in a solution originally 0.0010 M in Cr 3+ and 0.050 M in H 2 EDTA 2− and buffered at pH = 6.00.
