Lithium nitrate

CAS number : 7790-69-4

Molecular weight :68.94

Molecular formula/chemical symbol :LiNO3

Description :

The appearance of white tripartite crystalline. Soluble in water, ethanol, pyridine, ammonia. Their solution was neutral

Upon thermal decomposition, LiNO₃ gives lithium oxide (Li₂O), nitrogen dioxide, and oxygen:

4 LiNO₃ → 2 Li₂O + 4 NO₂ + O₂

Other group I nitrates decompose differently, forming the nitrite salt and oxygen. Because of its relatively small size, the lithium cation is very polarizing, which favors the formation of the oxide.

Lithium nitrate is also a very good oxidizing agent. Today LiNO₂ is used in submarines and spacecraft for absorbing excess carbon dioxide in the air.^[8]

LiNO₂ is also denser than water.

Lithium nitrate can be toxic to the body when ingested by targeting the central nervous system, thyroids, kidneys, and cardio-vascular system. When exposed to the skin, eyes, and mucous membranes, lithium nitrate can cause irritation to these areas.
