Polonium(IV) sulfate

Polonium(IV) sulfate is an inorganic compound with the chemical formula of Po(SO4)2. It forms colourless crystals, and is soluble in water. It can be obtained by the reaction of polonium tetrachloride (or hydrated polonium dioxide)[1] and sulfuric acid.[2] Polonium(IV) sulfate can be reduced to PoSO4[3] by hydroxylamine in acidic solutions; it decomposes to polonium dioxide at 550 °C. It is radioactive and produces gases as it decays.[2]
