Lithium Hydroxide
It is a white hygroscopic crystalline material.
It is soluble in water, and slightly soluble in ethanol
Lithium hydroxide is produced in a metathesis reaction between lithium carbonate and calcium hydroxide:

+ Ca(OH)

→ 2 LiOH + CaCO

The initially produced hydrate is dehydrated under vacuum up to 180 °C.
In the laboratory, lithium hydroxide arises by the hydrolysis of lithium or lithium oxide. The equations for these processes follow:
2 Li + 2 H
2
O → 2 LiOH + H

Li
2
O + H

O → 2 LiOH
Typically, these reactions are avoided.
