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, β₁₁=79±10, is somewhat larger than the theoretical results, β₁₁=55, predicted using the formation constants of PbBr₂ and PbCl₂. The molar absorptivity of PbBrCl was observed to be intermediate in character between the molar absorptivities of PbBr₂ and PbCl₂. Determinations of the formation constants of PbBr₂Cl⁻ and PbBrCl₂ ⁻ are in reasonable agreement with the predictions based on the formation constants of PbBr₃ ⁻ and PbCl₃ ⁻. Mixed ligand species dominated the complexation scheme of Pb(II) in our test media.
