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, MT. For higher ligand number mixed-ligand complexes it is found that ([MX2y]+ [MXY2)/MT 0.75 and ([MX3y] + [MX2Y2 ] + [MXY3] /MT 0.875. In high average ligand number systems, mixed complexes, MXaYb, can dominate a metal's solution chemistry even when only one single-ligand type species, MXa + b, is important. Mixed-ligand complexes may dominate the chemistry of highly associated hydrothermal solutions.
