Barium chloride, is an inorganic compound, chemical formula BaCl2, is a white crystal, soluble in water, slightly soluble in hydrochloric acid and nitric acid, insoluble in ethanol and ether, easy to absorb moisture, commonly used as analytical reagents, dehydrating agent, barium salt raw materials and used in electronics, instrumentation, metallurgy and other industries.

Barium chloride, slightly soluble in nitric acid and hydrochloric acid, almost reputation solubility for ethanol and ether, and barium chloride can be easily sealed off, so we generally use barium chloride as an analytical reagent, usually used in metallurgy and other industries.

The main use of barium chloride is now used as a metal heat treatment, and can be used for the manufacture of barium salt and the production of some electronic instruments. It can also be selected as a heat treatment agent in mechanical processing. Moreover, the determination of sulfate and selenate can also be used as a water softener and some fabric dyeing.

How to get barium chloride? First, it is necessary to dilute a 20 ml concentrated hydrochloric acid, add 20g barium carbonate while stirring, then add an aqueous solution of applying carbon dioxide and forming barium chloride, remove some insoluble components through filtered calligraphy, then heat and concentrate the filtered liquid in water, and finally form crystals of barium chloride after cooling. After filtering and natural air drying, a barium dichloride will be formed.

First of all, we must pay attention to the storage of barium chloride is the need for a cool and ventilated environment to store, do not store barium chloride in some places may encounter open fire, barium chloride packaging sealed, but also should be barium chloride and some oxidants, edible chemicals, acid and the like separate storage, can not be mixed up!
