Popis: The formation of chelates between aluminium(III) and 3-hydroxy-7-sulpho-2-naphthoic acid has been studied in aqueous solutions of various ionic strengths, at 298 K. The stability constants of AlL, AlL 2 and AlL 3 and the protonation constants of the ligand, obtained by potentiometry with the glass electrode, are compared with values found by absorption and fluorescence spectrophotometric methods.
