Calculate the concentration of Pb2+ in the following.
c. Ethylenediaminetetraacetate (EDTA4-) is used as a complexing agent in chemical analysis and has the following structure:
Solutions of EDTA4- are used to treat heavy metal poisoning by removing the heavy metal in the form of a soluble complex ion. The reaction of EDTA4- with Pb2+ is
Pb2+(aq) + EDTA4-(aq) ⇌ PbEDTA2-(aq) K = 1.1 X 10 18
Consider a solution with 0.010 mole of Pb(NO3)2 added to 1.0 L of an aqueous solution buffered at pH = 13.00 and containing 0.050 M Na4EDTA. Does Pb(OH)2 precipitate from this solution?
