Chemical compound
Rubidium bromide is an inorganic compound with the chemical formula RbBr. It is a salt of hydrogen bromide. It consists of bromide anions Br− and rubidium cations Rb+. It has a NaCl crystal structure, with a lattice constant of 685 picometres.[1]
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.
