Barium Bromide, Formula, Chemical Properties, Preparation, Uses

Barium Bromide

Barium bromide is a chemical compound and it dissolves in water and toxic. It looks like a deliquescent orthorhombic crystals. It can cause severe poisoning on ingesting and some other water soluble barium salts are considered as the toxic. It reacts with the oxygen, sulfur and carbon to form barium compounds. It should be the pure form of metallic alkaline in nature. The systematic IUPAC name is known as Barium bromide. The chemical or molecular formula of Barium bromide is BaBr2.

Structural Formula

This is the structural formula of the Barium bromide:

Barium Bromide

Chemical Formula

The chemical formula of the Barium bromide is BaBr2.

Preparation Method

When the barium sulfide is reacted with the hydrobromic acid it gives the result of formation of barium bromide. It gives the hydrogen sulfide as the byproduct. In another method the barium carbonate is reacted with the hydrobromic acid it gives the formation of barium bromide. Carbon dioxide and water is the byproduct.
