Questions And Answer

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.
Lithium sulfate
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.

Hazard Information

Definition
ChEBI: A metal sulfate in which the counterion is lithium and the ratio of lithium to sulfate is 2:1.
Purification Methods
Crystallise it from H2O (4mL/g) by partial evaporation, and dry it above 130o in vacuo.
