By the method of ion exchange on the exchanger Dowex 50
WX 8 100-200 mesh complex formation was investigated in the
system Me(ClO₄)₃ + XC₆H₄OH + HClO₄ + NaClO₄ + H₂O, with
Me = Fe(III) or Al(III) and X = Cl, Br, CH₃, NO₂. It was
proved that 1:1 complexes are formed between Me(III) and
a phenol molecule. Stability constants of the complexes
were determined and related with Hammett’s sigma constants.
