'''Lithium bromide''' LiBr is a [[chemical compound]] of [[lithium]] and [[bromine]]. Its extreme [[hygroscopic]] character makes LiBr useful as a [[desiccant]] in certain air conditioning systems.<ref name=Ullmann>Ulrich , Richard J. "Lithium and Lithium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry Wiley-VCH: Weinheim.</ref>

LiBr is prepared by of lithium carbonate with [[hydrobromic acid]]. forms several crystalline [[water of crystallization|hydrates]], unlike the other alkali metal bromides.<ref>HollemanWiberg</ref>

Lithium and ( solution of ) will precipitate in the presence of water.

LiOH + HBr → LiBr + H₂O

bromide is used in air-conditioning systems as [[desiccation|desiccant]]. a reagent in [[organic synthesis]]. it [[]]s .<ref name=Ullmann/>

Lithium bromide was used as a [[sedative]] beginning in the early 1900s, but it fell into disfavor in the 1940s when some heart patients died after using salt substitute.<ref>http://www.webmd.com/content/Article/87/99356.htm?pagenumber=1Bipolar </ref> Like [[lithium carbonate]] and [[lithium chloride]] it was used as treatment for [[bipolar disorder]].

[[Lithium salts]] are psychoactive and somewhat corrosive.
