Abstract
Experimentally and theoretically derived formation constants of mixed lead halide complexes are compared at 25.0°C and one molar ionic strength. The formation constant of PbBrCl, β 11 =79±10, is somewhat larger than the theoretical results, β 11 =55, predicted using the formation constants of PbBr 2 and PbCl 2 . The molar absorptivity of PbBrCl was observed to be intermediate in character between the molar absorptivities of PbBr 2 and PbCl 2 . Determinations of the formation constants of PbBr 2 Cl − and PbBrCl 2 − are in reasonable agreement with the predictions based on the formation constants of PbBr 3 − and PbCl 3 − . Mixed ligand species dominated the complexation scheme of Pb(II) in our test media.
