E-Z-PAQUE (barium sulfate) is a radiographic contrast agent that is supplied as a fine, white to lightly colored powder for suspension (96 % w/w) for oral administration. The active ingredient barium sulfate is designated chemically as BaSO 4 with a molecular weight of 233.4 g/mol, a density of 4.5 g/cm 3, and the following chemical structure:
Barium sulfate occurs naturally as the mineral barite, which was first investigated by a shoemaker who dabbled in alchemy, Vincenzo Casciarolo, who found some shiny pebbles near his home in Bologna, Italy, in the early 1600s. Heating these stones to redness bestowed upon them a rather curious property: they shone in the dark.
Barium sulfate (BaSO 4), often just called barium in radiology parlance, is an ionic salt of barium (Ba), a metallic chemical element with atomic number 56.

All barium compounds are toxic; however, barium sulfate is insoluble and so can be safely swallowed. A suspension of barium sulfate is sometimes given to patients suffering from digestive disorders. This is a 'barium meal' or 'barium enema'. Barium is a heavy element and scatters X-rays, so as it passes through the body the stomach and ...
Barium sulfate is not innocuous when aspirated but causes a less severe pneumonitis. Contraindications. Barium swallow studies should be used in cases of suspected esophageal perforation only after considering the risk of inflammatory mediastinitis. This is not an absolute contraindication and should be weighed against the …
Barium enema: A barium enema is an X-ray exam that can detect changes or abnormalities in the large intestine (colon). The procedure is also called a colon X-ray.
fast or slow heartbeat. hives or welts, itching, or skin rash. noisy breathing. persistent bleeding or oozing from puncture sites, mouth, or nose. redness of the skin. sweating. unusual tiredness or weakness. Some side effects may occur that usually do not need medical attention.
Barium sulfate is extremely insoluble and very little, if any, ingested barium sulfate is absorbed. Acid-soluble barium compounds, such as barium chloride and barium carbonate, are absorbed through the gastrointestinal tract, although the amount of barium absorbed is highly variable.
The ready formation of a precipitate indicates that barium sulfate is quite insoluble. In fact, 1 liter of water dissolves about 2 mg of barium sulfate at room temperature. Solubility of the carbonates. The carbonates become less soluble down the group. All the Group 2 carbonates are very sparingly soluble.
Barium sulfate is a chemical compound with the formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. Barium sulfate is commonly used in various industries due to its unique properties.It has a high density, making it useful as a contrast agent in X-ray imaging procedures.Additionally, it is chemically inert, non …
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, BaSO 4) and witherite ( barium carbonate ...
Barium sulfate is a significant inorganic chemical with several applications, including medical uses. Structure and Formula of barium sulfate: The chemical formula of barium sulfate is BaSO4 and its molar mass is 233.43 g/mol. It is a salt made up of the barium cation (Ba2+) and the sulfate anion (SO42-), in which sulfur is joined to four ...
