Abstract: In this paper we have studied the existing state of terbium (Ⅳ) oxide hydrate in HCl, HNO3, HClO4 and HAc solutions. Through the investigations of the optical and electrical properties and coagulation values it is showed that the Terbium (Ⅳ) oxide hydrate exists as a sol with positive charges in these solutions. The UVand visible absorption spectra and kinetics of reduction of the sols have also been studied.
