| Questions And Answer | Back Directory | [Chemical Properties]
Lithium sulfate is a colorless monoclinic or hexagonal crystalline solid. It is the lithium salt of sulfuric acid. Although lithium sulfate solution is prepared in a large quantity as an intermediate in the spodumene-sulfuric acid process, the pure compound has only limited industrial use. It is used in small quantities in molten salt baths for the chemical strengthening of glass.
The dissolved lithium sulfate is converted into lithium carbonate by adding sodium carbonate (NaCO3).The sodium replaces the lithium in the sulfate compound.This reaction works this way because sodium is more reactive than lithium.
| [Uses]
Lithium sulfate is used in making a special type of high strength glass. It
also is used in medicine as an antidepressant. | [Preparation]
Lithium sulfate is prepared by neutralization of lithium hydroxide or lithium carbonate with sulfuric acid followed by crystallization:
2LiOH + H2SO4 → Li2SO4 + H2O
Li2CO3 + H2SO4 → Li2SO4 + CO2 + H2O
The product obtained from crystallization in a concentrated solution is the monohydrate, Li2SO4•H2O. Anhydrous salt is obtained by heating the monohydrate in a vacuum.
