Abstract

The hydrolysis reactions of AlCl~3~ in 0.1 M aqueous solutions at pH 3.27–4.20 were monitored by electrospray ionization time‐of‐flight mass spectrometry (ESI‐ToF MS) as a function of time. The cationic and anionic ESI mass spectra of aluminum(III) solutions gave strong evidence of the presence of a variety of monomeric and polymeric complexes. Competition between the OH^−^ and Cl^−^ ligands within the same aluminum core was observed. The influence of the sample cone voltage on the product distribution was also explored. The optimum sample cone voltage for the cationic spectra was 70 V. For the anionic spectra no optimum sample cone voltage was found and the appearance of the anionic spectra was strongly dependent on the sample cone voltage within the whole range explored.
