RUBIDIUM BROMIDE Chemical Properties,Uses,Production
Description
Rubidium bromide (RbBr) is a hygroscopic material, which is generally similar to the other rubidium halides.
Rubidium bromide is the bromide of rubidium. It has a NaCl crystal structure, with a lattice constant of 685 picometres.
There are several methods for synthesising rubidium bromide. One involves reacting rubidium hydroxide with hydrobromic acid:
RbOH + HBr → RbBr + H2O
Another method is to neutralize rubidium carbonate with hydrobromic acid:
Rb2CO3 + 2 HBr → 2 RbBr + H2O + CO2
Rubidium metal would react directly with bromine to form RbBr, but this is not a sensible production method, since rubidium metal is substantially more expensive than the carbonate or hydroxide; moreover, the reaction would be explosive.
Chemical Properties
white crystalline powder
Uses
Rubidium bromide is used in infrared optics.
Synthesis
There are many ways to synthesize rubidium bromide. One is the reaction of rubidium hydroxide with hydrogen bromide: RbOH + HBr → RbBr + H2O ;
Another method is to neutralize rubidium carbonate with hydrogen bromide: Rb2CO3 + 2HBr → 2RbBr + H2O + CO2
Purification Methods
The bromide is a white crystalline powder which crystallises from H2O (solubility: 50% in cold and 67% in boiling H2O to give a neutral solution). It also crystallises from near-boiling water (0.5mL/g) by cooling to 0o.
