Lithium nitrite is a compound that is very soluble in water, meaning that it is hygroscopic. It is the lithium salt formed from nitrous acid.
Under certain conditions, it can become a potential agent of manufacturing explosives. This compound is also used in mortar as a corrosion inhibitor.
Lithium nitrite is also known as nitrous acid. Its molecular formula is LiNo2. To acquire lithium nitrite crystals, barium nitrite and lithium sulfate are reacted in an aqueous solution. The lithium crystals can also be made in a properly concentrated aqueous solution where equal amounts of potassium nitrite and lithium sulfate are mixed together.
