Rubidium Iodide
Rubidium iodide is a salt with a melting point The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depen ... of 642 °C. Its chemical formula is Rb I. Rubidium iodide can be formed from the reaction of rubidium and iodine: :2 + → 2 References * ''CRC Handbook of Chemistry and Physics'', 77th edition Rubidium compounds Iodides Metal halides Alkali metal iodides Rock salt crystal structure {{inorganic-compound-stub ...

Rubidium Fluoride
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. One involves reacting rubidium hydroxide with hydrofluoric acid: :RbOH + HF → RbF + H2O Another method is to neutralize rubidium carbonate with hydrofluoric acid: :Rb2CO3 + 2HF → 2RbF + H2O + CO2 Another possible method is to react rubidium hydroxide with ammonium fluoride: :RbOH + NH4F → RbF + H2O + NH3 The least used method due to expense of rubidium metal is to react it directly with fluorine gas, as rubidium reacts violently with halogen The halogens () are a group in the periodic table consisting of five or six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). In the modern IUPAC nomenclature, this group is ...s: :2Rb + F2 → 2RbF References * Rubidium compounds Fluorides Alkali metal fluorides Rock salt crystal struct ...
