Rubidium hydride
Encyclopedia
Rubidium hydride is the hydride
of rubidium
. It is synthesized using rubidium metal to react with hydrogen
gas. As a hydride of an alkali metal
, it is reactive towards even weak oxidizing agent
s. A redox
reaction will occur with chlorine
or fluorine
and a lot of heat will evolve. Rubidium hydride will react violently with water or air and careful storage is necessary.
Hydride
In chemistry, a hydride is the anion of hydrogen, H−, or, more commonly, a compound in which one or more hydrogen centres have nucleophilic, reducing, or basic properties. In compounds that are regarded as hydrides, hydrogen is bonded to a more electropositive element or group...
