and all otherfluoride sRubidium fluoride (RbF) is the
fluoride salt ofrubidium . It is anoctahedral crystal .There are several methods for synthesising rubidium fluoride. One involves reacting
rubidium hydroxide withhydrofluoric acid ::RbOH + HF → RbF + H2OAnother method is to neutralizerubidium carbonate with hydrofluoric acid::Rb2(CO3) + 2HF → 2RbF + H2O + CO2The least used method due to expense of rubidium metal is to react it directly with fluorine gas, as rubidium reacts violently withhalogen s::2Rb + F2 → 2RbFReferences
