Catalyst support
Barium sulfate is a low surface area material used as a support for selectively hydrogenating functional groups sensitive to overreduction. With a low surface area, the contact time of the substrate with the catalyst is shorter. A supported palladium catalyst on barium sulfate, and doped (poisoned) with quinoline hydrogenates alkynes into cis-alkenes. Alkenes are liable to be hydrogenated further into alkanes, which reaction the special support and poison prevent.
Radiocontrast agent
Barium sulfate is frequently used clinically as a radiocontrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as a 'barium meal'.
It is administered, orally or by enema, as a suspension of fine particles in an aqueous solution (often with sweetening agents added). Although barium is a heavy metal, and its water-soluble compounds are often highly toxic, the extremely low solubility of barium sulfate protects the patient from absorbing harmful amounts of the metal. Barium sulfate is also readily removed from the body, unlike Thorotrast, which it replaced. Due to the relatively high atomic number (Z = 56) of barium, its compounds absorb X-rays more strongly than compounds derived from lighter nuclei.
Pigment
Barium sulfate mixtures are used as white pigment for paints. In oil paint, barium sulfate is almost transparent,and is used as a filler or to modify consistency. One major manufacturer of artists' oil paint sells "permanent white" that contains a mixture of titanium white pigment and barium sulfate. Barium sulfate itself is called blanc fixe (French for "permanent white"). The combination of barium sulfate and zinc sulfide (ZnS) is called lithopone.
Pyrotechnics
Barium sulfate is commonly used as a component of "strobe" pyrotechnic compositions.
Barium sulfate is also used as a high temperature oxidizer in certain pyrotechnic formulas, as barium compounds emit a green light when burned. Barium nitrate is more common in green pyrotechnic formulas, as it contains an oxidizer while still producing green colored light.
Other uses
Barium sulfate is used as a filler in plastics and as a component of oil well drilling fluid to increase the density. It is also used in Episal salt, brake linings, anacoustic foams, powder coatings, and root canal filling.
Barium sulfate is also used during the procedure of the soil pH test. In this test it is used so that it precipitates out any particles (usually clay particles) which would otherwise 'cloud' solution preventing one from seeing the colour of the pH indicator i.e. the result of the test.
In colorimetry barium sulfate is used as a near-perfect diffuser when measuring light sources.
In Photography it is used as a coating for certain photographic papers.
In metal casting, the moulds used are often coated with barium sulfate in order to prevent the molten metal from bonding with the mould.
The reagents needed to form barium sulfate are barium chloride and sodium sulfate. When these two compounds are mixed in solution, a white precipitate of barium sulfate forms.
Barium sulphate to barium sulphate is NO CHANGE!
Barium sulfate is thermally decomposed in barium oxide and sulfur trioxide.
Yes, barium sulfate is sometimes used in medical imaging procedures such as a barium swallow or barium meal. However, it is not typically referred to as a "chalk drink" as it does not serve the same purpose as consuming chalk.
Barium doesn't have a lot of uses, but barium sulfate is used in medicine as a contrast agent in some imaging.
The compound BaSO4 is known as barium sulfate. Because of its white color, it is sometimes used for pigmentation, especially in paper.
The reagents needed to form barium sulfate are barium chloride and sodium sulfate. When these two compounds are mixed in solution, a white precipitate of barium sulfate forms.
Barium sulfate
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
Barium sulphate to barium sulphate is NO CHANGE!
Yes, when barium acetate and lithium sulfate are mixed, a white precipitate of barium sulfate would form due to a double displacement reaction. This is because barium sulfate is insoluble in water.
Barium chloride is commonly used as a precipitating agent to precipitate sulfate ions as insoluble barium sulfate. This reaction is often utilized in analytical chemistry to detect the presence of sulfate ions in a solution.
When you add sodium sulfate to barium chloride, a white precipitate of barium sulfate forms. This is due to the reaction between sodium sulfate and barium chloride, which forms insoluble barium sulfate.
the symbol for barium sulfate is Ba(SO4)2
When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.
Barium chloride can be precipitated wit a sulfate; barium sulfate is then filtrated.
Barium sulfate is thermally decomposed in barium oxide and sulfur trioxide.
