Chemical compound
Radium iodate is an inorganic compound, a salt of radium and iodic acid with the chemical formula Ra(IO3)2.[2][3][4]
Synthesis
Radium iodate is obtained by the reaction of a soluble radium salt and potassium iodate:[5]
- RaCl2 + 2KIO3 → Ra(IO3)2 + 2KCl
Physical properties
Radium iodate forms colorless crystals. It is poorly soluble in water.[1][6]
