  2. Barium sulfate - Wikipedia

    en.wikipedia.org/wiki/Barium_sulfate

    Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water . It occurs in nature as the mineral barite , which is the main commercial source of barium and materials prepared from it.

  3. Barium sulfate suspension - Wikipedia

    en.wikipedia.org/wiki/Barium_sulfate_suspension

    The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6] In the United States it had come into common medical use ...

  4. Baryte - Wikipedia

    en.wikipedia.org/wiki/Baryte

    Baryte. Baryte, barite or barytes (/ ˈbæraɪt, ˈbɛər -/ BARR-eyet, BAIR-[7] or / bəˈraɪtiːz / bə-RYTE-eez[8]) is a mineral consisting of barium sulfate (Ba S O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium. The baryte group consists of baryte, celestine (strontium sulfate), anglesite ...

  5. Barium chloride - Wikipedia

    en.wikipedia.org/wiki/Barium_chloride

    Infobox references. Barium chloride is an inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium. Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame.

  6. Barium - Wikipedia

    en.wikipedia.org/wiki/Barium

    Barium. body-centered cubic (bcc) (cI2) Barium is a chemical element; it has symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The most common minerals of barium are barite (barium sulfate ...

  7. Upper gastrointestinal series - Wikipedia

    en.wikipedia.org/wiki/Upper_gastrointestinal_series

    An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium, usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...

  8. Barium acetate - Wikipedia

    en.wikipedia.org/wiki/Barium_acetate

    Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2] BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes.

  9. Sulfate - Wikipedia

    en.wikipedia.org/wiki/Sulfate

    Radium sulfate is the most insoluble sulfate known. The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to ...
