    CAS No.: 7789-39-1 Formula: BrRb Molecular Weight: 165.37200

    Description

    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 + 2HBr → 2RbBr + 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.
