Lithium Chloride, Formula, Chemical Properties, Preparation, Uses

Lithium Chloride

Lithium chloride is a chemical compound and it has consists of lithium as positive charged and chloride as the negative charged. It has in the form of anhydrous state. In the polar solvents it acts as the extraordinary chemical compounds. The lithium ion has increase their properties compared to the other alkaline metal chlorides. The systematic IUPAC name is known as lithium chloride . The chemical or molecular formula of lithium chloride is LiCl. It is also known as chlorolithium or lithiumchlorid.

Structural Formula

This is the structural formula of the lithium chloride:

Lithium Chloride

Chemical Formula

The chemical formula of the lithium chloride is LiCl.

Preparation Method

It can be prepared by the reaction between the lithium carbonate with the hydrochloric acid and it gives the lithium chloride as product and hydrogen carbonate as byproduct. In the another way it is highly heated and induced between lithium metal with the anhydrous hydrogen chloride gas or chlorine.  Also it is obtained by the steamed the hydrogen chloride by heating on it in the anhydrous form.
