Compound Name - Lithium Hydroxide

Formula - LiOH

Molar Mass - 23.95 g/mol

Melting Point - 450-470 °C

Boiling Point - 924 °C (decomposes)

Density in Natural State - 1.46 g/cm3 as a solid

Where is it found? - Lithium makes up about 0.002% of the earth's crust, but it is normally extracted as lithium hydroxide and other lithium compounds (such as carbonate and sulfate).

What is its natural abundance?
- N/A

How is it obtained?
- Lithium hydroxide can be obtained by dissolving lithium or lithium oxide in water. It is commonly obtained by the reaction of lithium carbonate with lime.

Chemical Properties/Reaction Tendencies

Lithium Hydroxide appears as an odorless, white crystalline solid. It is stable under normal conditions of use and storage. The compound is soluble; when exposed to air, the lithium hydroxide reacts with carbon dioxide. When lithium hydroxide is decomposed it emits toxic fumes. Lithium Hydroxide reacts with water, carbon dioxide, strong acids, aluminum, zinc, and strong oxidizers.
