Barium Chloride, Formula, Chemical Properties, Preparation, Uses

Barium Chloride

Barium chloride is an inorganic salt that has the combination of barium and chloride. It is toxic at naturally. The barium acts as the cations and the chloride acts as the anions. Barium chloride is a hygroscopic and blow at the yellow green colour when it is put at the furnace.  The systematic IUPAC name is known as Barium chloride. The chemical or molecular formula of Barium chloride is BaCl2.

Structural Formula

This is the structural formula of the Barium chloride:

Barium Chloride

Chemical Formula

The chemical formula or molecular formula is BaCl2.

Preparation Method

Take the concentrated hydrochloric acid 180ml when it is diluted with the 400ml of water. the barium carbonate is mixture with the hydrochloric acid in the vessel. When the solution is neutral to litmus then it will be boiling. This barium carbonate is cosists the iron as an impurity. By adding the 3g of barium peroxide then the solution is heated for half an hour. Then this solution is prevented from the crystallization and it will be cooling. At the room temperature the distilled water is crystallized under the dilute hydrochloric acid.
