Chemical compound

Rubidium fluoride (RbF) is the fluoride salt of rubidium. It is a cubic crystal with rock-salt structure.

There are several methods for synthesising rubidium fluoride. Ane involves reacting rubidium hydroxide with hydrofluoric acid:^[1]

RbOH + HF → RbF + H₂O

Some other method is to neutralize rubidium carbonate with hydrofluoric acrid:^[1]

Rb₂CO₃ + 2HF → 2RbF + H_iiO + CO₂

Some other possible method is to react rubidium hydroxide with ammonium fluoride:

RbOH + NH₄F → RbF + H₂O + NH_three

The least used method due to expense of rubidium metal is to react it direct with fluorine gas, equally rubidium reacts violently with halogens:^[1]

2Rb + F_ii → 2RbF
