[Chemical Knowledge]：The Difference and Application of Barium Sulfate and Barium Chloride

Read： 629 Time：17months ago Source：Transform the World with Simplicity

Barium sulfate and barium chloride are two common barium salt compounds, which have certain differences in chemical properties and application fields.

from the chemical composition, the chemical formula of barium sulfate is BaSO4, and the chemical formula of barium chloride is BaCl2. It can be seen that they are formed by combining sulfate and chloride ions with barium ions, respectively. The sulfate ion in barium sulfate is an anion, while the chloride ion in barium chloride is an anion, which is their primary difference.

in the chemical nature, barium sulfate and acid reaction can generate insoluble in water barium sulfate precipitation, this nature makes barium sulfate can be used as a precipitation reagent to separate and detect the presence of sulfate ions. When barium chloride reacts with sodium salts such as sodium sulfate, it can form precipitated barium chloride, so it can also be used as a reagent in analytical chemistry. In addition, barium chloride can also be used to prepare other barium chloride salts.

from the application field, barium sulfate is often used in papermaking, coatings, rubber, plastics and other industries as a filler and whitening agent. Barium chloride is often used in metal surface treatment, photographic technology, spark plug manufacturing and so on. Therefore, although barium sulfate and barium chloride are different in chemical properties, their application value in different fields cannot be ignored.

In summary, although barium sulfate and barium chloride have certain differences in chemical composition and chemical properties, they have their own advantages and characteristics in practical applications. This also provides more possibilities for our choices in production and research.
