Barium Chloride Formula

Barium Chloride Formula

The Barium Chloride Formula salt is an inorganic salt formed by the direct reaction of barium (Ba) and chlorine (Cl). It is also known as barium muriate or barium dichloride. Furthermore, it is a white solid that dissolves when placed in water. It is hygroscopic and gives the flame a slight yellow and green colour. Furthermore, the chemical formula for Barium Chloride is BaCl2. In the industrial sector, barium salts are widely used. Sulphate is commonly used in white paints that are intended for outdoor use. In nature, however, barium chloride is poisonous and harmful.

Structural Formula Of Barium Chloride (Barium dichloride)

Barium Chloride Formula has the chemical formula BaCl2 and a molar mass of 208.23 g mol-1. This salt is composed of a barium cation (Ba2+) and a chlorine anion (Cl–). Furthermore, the barium salt has a dehydrate form with a molar mass of 244.26 g mol-1.

The crystals can be cubic, fluorite, or orthorhombic. Its chemical structure is shown below in the form of an image in the common representations that we use for organic molecules.

Barium chloride does not occur naturally. Barium Chloride can be easily obtained by roasting barite with coal and calcium chloride.


Barium chloride can be produced by conducting a two-step reaction from barium sulphate to produce the barium sulphate, which reacts with HCl to produce barium chloride:

BaSO4+ 4C → BaS + 4CO

BaS + 2HCl → BaCl2+ H2S

Barium Chloride can also be made from barium sulphide, which is hydrochloric acid.

Physical Properties

The Physical properties of Barium Chloride Formula is given below:

The density of Barium Chloride Formula is 3.856 g mL-1, and it is a white solid. Barium chloride has melting and boiling points of 962 °C and 1560 °C, respectively. It is easily soluble in water (H2O), methanol, but insoluble in ethanol and ethyl acetate. It has a slightly yellow and green flame, but it is extremely toxic in nature.

Chemical Properties

The Chemical properties of Barium Chloride Formula are given below:

The chemical properties of Barium Chloride are the same as any other binary salt of chlorine. It decomposes in water (H2O) to produce:

BaCl2→ Ba2+ + 2Cl–

This reaction is similar to other binary Cl salts such as NaCl and has no effect on the pH of the solutions.


Because it produces a green flame, barium chloride is useful in the fireworks’ industry. It is also used in the treatment of heat-produced salts. Barium chloride is also used in the petroleum industry. In general, its toxicity limits its application in the laboratory.

Health Effects and Safety Hazards

Some chemicals have various health hazards which should be kept in mind. The various Health effects of Barium Chloride Formula are given below:

In nature, Barium Chloride Formula is extremely toxic. It is toxic by ingestion and inhalation and can cause serious eye damage. It is also harmful to aquatic life and animals.
