Abstract | Exchange reactions between multidentate ligands (also known as chelating agents) contribute to kinetic control of metal ion speciation in aquatic environments. However, the complexity of the stepwise reaction mechanism complicates predictions of kinetic behavior (rates, rate laws, and mechanisms). Clarity is achieved with the adjunctive-semijunctive-disjunctive paradigm, which categorizes multidentate ligand exchange pathways along a continuum according to the decreasing ease of forming intermediate mixed-ligand ternary complexes. In order to better understand how steric interaction between entering and leaving ligands affects reaction pathways and kinetic behavior, we use a capillary electrophoresis method to monitor exchange between |
