FORMATION OF ALUMINUM(III)-MONOCARBOXYLATES IN AQUEOUS-SOLUTION

By means of stopped-flow experiments equilibrium and rate constants are determined for the weak complexation of the aluminium(III)-ion with formate, acetate, chloroacetate and benzoate. For the inner-sphere complex formation both equilibrium and rate constants depend on the nature of the ligand, and a linear free energy relation is observed between rate constants and dissociation constants of the corresponding acids.
