Lithium Chloride - LiCl

What is Lithium Chloride?

Lithium Chloride is a white solid hygroscopic soluble in water, alcohol and ether. The chemical formula for lithium chloride is LiCl. It is made by the action of hydrochloric acid on lithium hydroxide. The resulting solution is evaporated to get a mixture of saturated solution and lithium chloride crystals. The solid and the solution is separated and the supernatant solution is recycled for further evaporation. Lithium chloride is a solid which absorbs water to form a hydrate, LiCl.H₂O

Physical Properties of Lithium Chloride – LiCl

Chemical Properties of Lithium Chloride – LiCl

• • Lithium chloride reaction with sulfuric acid forms lithium sulfate and hydrogen chloride. The chemical equation is given below.

2LiCl + H₂SO₄ → 2 HCl + Li₂SO₄

• • Lithium chloride reacts with a base like sodium hydroxide and forms lithium hydroxide and sodium chloride.

LiCl + NaOH → LiOH + NaCl

Uses of Lithium Chloride – LiCl

• Used in large dehumidification systems in the air conditioning industry. It depends on the low equilibrium pressure of water vapour above solutions of lithium chloride.
• Used in a number of salt mixtures exist low melting points allowing the material to be used in brazing fluxes and brazing baths.
• Used as an electrolyte for the production of lithium metal and used as an electrolyte in voltaic cells.
