Barium chloride, also commonly known as Barium muriate, is an inorganic compound with the formula BaCl2. Barium chloride is one of the most common water-soluble barium salts, which is produced by the reaction of Hydrochloric acid and Barium carbonate or barium sulfide. Like other barium salts, it is toxic and gives a flammable yellow-green color. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.
Physical and Chemical Properties:
Barium chloride with the chemical formula BaCl2 is an ionic chemical compound and is one of the most important water-soluble salts. The compound appears as a white, toxic powder that gives the flame a yellow-green color. It is a moisture absorber and by absorbing water, it is converted to barium dihydrate chloride and has limited use in laboratories and industries. Barium chloride is not found in nature, is soluble in water and methanol, and is insoluble in ethanol and ethyl acetate. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Barium Chloride Solubility:
Barium chloride is completely soluble in water (like most ionic salts). It is an ionic compound that readily dissociates into its ions in water. At 20 ° C, the solubility of this compound in water depends on temperature. At 20℃, the solubility of barium chloride in water is 357 g / l. This compound is also soluble in methanol (although not soluble in ethanol).
Barium Chloride Polar or Nonpolar:
Barium chloride dissolves easily in water and due to its presence in the metal group II, it does not have a 180-degree bond angle. These properties indicate the polarity of this salt.
The Production Process of Barium Chloride:
It is generally produced by the reaction of hydrochloric acid and barium carbonate or barium sulfide. If barium sulfide is used, a very toxic gas, hydrogen sulfide, is produced, which requires additional purification steps. The use of hydrochloric acid can also cause corrosion problems.
BaSO4 + 4 C → BaS + 4 CO
BaS + 2 HCl → BaCl2 + H2S
Barium Chloride Uses:
Although barium chloride is inexpensive, it has limited applications in industry and laboratories. In fact, the toxicity of this substance reduces its applications.
- It is commonly used in the laboratory to test for sulfate ions.
- In the industry, the process of producing caustic soda is commonly used for the purification of saline solution, also in the manufacture of heat treatment salts, the production of pigments, and in the field of barium salts.
- Barium chloride produces colored flames when it catches fire, usually yellow and green. This chemical compound is used to produce a variety of incendiary materials for fireworks.
- There are different types of barium chloride. One of those types is barium chloride-coated water. This chemical product has stabilizing properties and is used in the manufacture of very strong PVC polymers.
- Production of electronic tools.
- Calibration tools and equipment, quality assurance, quality control.
- It is used in the petroleum industry.
- Used in the steel industry to harden steel.
- Other applications of this material in water treatment and wastewater treatment, oil lubricants, barium chromate, and barium fluoride were mentioned.
Safety Information of Barium Chloride:
Barium chloride is one of the toxic and dangerous chemical compounds for humans. Therefore, its use requires observance of the basic principles of care. Poisoning with this compound causes delirium, esophageal irritation, stomach pain, abdominal cramps, nausea, vomiting, diarrhea, high blood pressure, muscle weakness, vision and speech problems, difficulty breathing, dizziness, tinnitus, and more.
- In case of contact with eyes, rinse immediately with plenty of water. If inhaled, remove the poisoned person from the contaminated environment and take them to the open air and contact medical centers. It is also toxic to aquatic life and its antidote is magnesium or sodium sulfate.
- If you swallow barium chloride, rinse your mouth with water and seek medical attention immediately, as the substance dissolves and is rapidly absorbed in water, so symptoms appear quickly and can cause cardiac and respiratory arrest.
- Also, all people in connection with this chemical compound should use special glasses and masks. Because the gases emitted from this chemical compound can be very dangerous and inhalation can be deadly.
Packing and Storage:
Store in suitable, labeled containers, in a cool, dry, well-ventilated area, out of direct sunlight and away from incompatible materials.
