| RUBIDIUM BROMIDE Usage And Synthesis |
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. | 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. |
