title: The stability constants of PdeDTA and its chloride complexes.
abstract: From the position of the equilibrium Th + PdEDTA <--> Pd + ThEDTA, the stability constant of PdEDTA can be related to that for ThEDTA. If log k(ThEDTA) = 25.3 is taken as the most reliable value currently available, log k(pdEDTA) = 25.6 +/- 0.2 is found (NaClO(4) medium, 21 +/- 1 degrees ). Repetition of the experiments at different chloride concentrations gives an estimated log K = 5.3 +/- 0.1 for the equilibrium PdEDTA+Cl(-) <--> PdEDTACl(-). The stability constants of ThEDTA and PdEDTA are not very dependent on ionic strength in the range 0.1-1.0.
