We have proposed and experimentally tested a phenomenological model of SO42- sulphate anions effect on the titania nucleation during hydrolysis of titanium tetrachloride. Sulphate anions form the chelating bidentate complexes with primary [Ti(OH)h(OH2)6-h](4-h)+ with the influence on the next olation process and promotion of anatase phase nucleation.
