Behaviour of some uranium(VI) compounds in disulphuric acid

Abstract

Uranium(V1) oxide, uranyl sulphate, uranyl carboxylates and uranyl chloride form UO₂(HS0₄)₂ when dissolved in disulphuric acid which polymerizes at higher concentrations. Uranium(V1) chloride gets solvolysed to form the acids H [U(HS0₄)₇] or H₂ [U(HS0₄)₈] which behave as non-electrolytes in disulphuric acid.
