Radium Chloride, RaCl2






Radium Chloride, RaCl2, may be obtained as the dihydrate, RaCl2.2H2O, by dissolving the carbonate in hydrochloric acid and allowing to crystallise. It may be dehydrated by heating to 100° C. in a platinum crucible for several hours, but it is not decomposed if the temperature be raised to 200° C. It is less soluble in water than barium chloride, and is precipitated by hydrochloric acid and by alcohol.
