Thallium(III) hydroxide is a very weak base; it dissociates to give the thallium(III) ion, Tl3+, only in strongly acidic conditions.

Preparation

Thallium(III) hydroxide can be produced by the reaction of thallium(III) chloride with sodium hydroxide[1] or the electrochemical oxidation of Tl+ in alkaline conditions.[2]
