Abstract

Theoretical considerations allow the calculation of the potential significance of mixed-ligand solution complexes. It can be shown that the solution concentration, [MXY], of a chemical species, MXY, cannot represent more than 50% of a metal's total dissolved concentration, M_T. For higher ligand number mixed-ligand complexes it is found that ([MX₂y]+ [MXY₂)/M_T 0.75 and ([MX₃y] + [MX₂Y₂ ] + [MXY₃] /M_T 0.875. In high average ligand number systems, mixed complexes, MX_aY_b, can dominate a metal's solution chemistry even when only one single-ligand type species, MX_{a + b}, is important. Mixed-ligand complexes may dominate the chemistry of highly associated hydrothermal solutions.
