Scandium iodate, Sc(IO₃)₃

Scandium iodate, Sc(IO₃)₃.18H₂O, from scandium chloride and potassium iodate, is a white, crystalline powder almost insoluble in water, but soluble in nitric acid. When dried at 250° it becomes anhydrous; at intermediate temperatures, hydrates with 15H₂O, 13H₂O, and 10H₂O may be obtained (Crookes).
