Molecular formula/chemical symbol :RbF
Description :
Keywords:Fluoride
Rubidium fluoride (RbF) is the fluoride salt of rubidium. It is an octahedral crystal.
There are several methods for synthesising rubidium fluoride. One involves reacting rubidium hydroxide with hydrofluoric acid:
RbOH + HF → RbF + H2O
Another method is to neutralize rubidium carbonate with hydrofluoric acid:
Rb2(CO3) + 2HF → 2RbF + H2O + CO2
The least used method due to expense of rubidium metal is to react it directly with fluorine gas, as rubidium reacts violently with halogens:
2Rb + F2 → 2RbF
