Radium iodide is an inorganic compound of radium and iodine with the chemical formula RaI2.[1][2] It is the radium salt of hydrogen iodide, consisting of radium cations Ra2+ and iodide anions I−.
Synthesis
[edit]The salt is synthesized by the reaction of radium carbonate with hydroiodic acid:[1]
- RaCO3 + 2 HI(aq) → RaI2 + H2O + CO2
