Lithium Bromide (LiBr)
Lithium Bromide (Pronunciation: Lith-ee-um Bro-mide) is a chemical compound of lithium and bromine. It is a white crystalline salt that is highly soluble in water.
Etymology
The term "Lithium Bromide" is derived from its constituent elements. "Lithium" comes from the Greek word "lithos" meaning stone, as it was first discovered in a mineral, while "Bromide" is derived from the Greek "bromos" meaning stench, referring to the strong smell of elemental bromine.
Uses
Lithium Bromide is primarily used in air conditioning systems as a desiccant because of its hygroscopic nature. It is also used in pharmaceutical preparations and as a sedative, although its use in medicine has declined due to the development of safer drugs.
