Francium chloride is a radioactive chemical compound with the formula FrCl. It is a salt predicted to be a white solid and is soluble in water. Its properties resemble caesium chloride.
Production
It is produced by the reaction of hydrochloric acid with francium metal:
:2Fr + 2HCl → 2FrCl + H2
It is also expected to be produced by the violent reaction of francium and chlorine gas.{{cite book |author1=Paul Collison |title=Nelson Modular Science |date=2003 |publisher=Nelson Thornes Limited |isbn=9780748767977 |page=130 |language=en}}
