May 08 2019Barium sulfate is a contrast agent Barium sulfate works by coating the inside of your esophagus stomach or intestines which allows them to be seen more clearly on a CT scan or other radiologic (x-ray) examination Barium sulfate is used to help diagnose certain disorders of the esophagus stomach or intestines
Jan 20 2008Thiophene is a liquid compound of the elements C H and S A sample of thiophene weighing 7 96 mg was burned in oxygen giving 16 65 mg CO2 Another sample was subjected to a series of reactions that transformed all of the sulfur in the compound to barium sulfate
Barium Sulfate / Barite Precipitated Barium Sulfate is inert resistant to light and weathering and insoluble in water acids alkali and organic media Pigment Grade These fine white barites are natural select white high quality material designed for use in paints and coatings plastics and other applications requiring a white and/or acid
The compound that contains both barium and nitrate ions is called barium nitrate and has the formula Ba(NO3)2 The compound that contains both copper(II) ions and sulfate ions is called copper(II) sulfate (or cupric sulfate) and has the formula CuSO4
BaSO 4 is an inorganic compound with the chemical name Barium Sulfate It is composed of a barium cation and the sulfate anion The sulfur is attached to four oxygen atoms BaSO 4 is a sulfate salt of barium and is found as mineral barite It is a crystalline solid white in color which is insoluble in water and alcohol but soluble in concentrated acids It is odorless Barium Sulfate is an alkaline divalent metal
After the barium and sulfate ions combine to form the solid barium sulfate precipitate the copper(II) ions and the nitrate ions remain in solution This representation is called the complete ionic equation The barium and sulfate ions actually react to form the barium sulfate product
Solubility Products of Selected Compounds 1 All sodium potassium and ammonium salts are soluble 2 All nitrates acetates and perchlorates are soluble 3 Most chlorides bromides and iodides are soluble except Silver and Mercury 4 All carbonates sulfides oxides and hydroxides are insoluble 5 All sulfates are soluble except calcium sulfate and barium sulfate
Barium chromate(VI) is the only compound recognized as carcinogenic in man Mutagenesis Barium chloride dihydrate was not mutagenic in Salmonella typhimurium nor did it induce sister chromatid exchanges or chromosomal aberrations in cultured Chinese hamster ovary cells
in aqueous solution to form barium sulfate in the introduction 2) Suggest a reason why it is desirable to use an excess of barium ion in the precipitation 3) A sample of an unknown sulfate compound has a mass of 0 1000 g to the sample forms a barium sulfate precipitate of mass 0 0676 g
Barium carbonates are mainly used to remove sulfate ion impurities and to introduce barium oxide into special fine glassware such as cathode tube television screens The production pathway of barium and barium compounds typically starts from barite Volatile barium compounds impart a pale green color to flames and this is an effective simple

Barium sulfate (BaSO 4) a common barium compound is used as a filler for rubber plastics and resins It can be combined with zinc oxide (ZnO) to make a white pigment known as lithophone or with sodium sulfate (Na 2 SO 4 ) to make another white pigment known as blanc fixe
The major barium compounds and their primary uses are as follows (1) Lithopone is a white powder consisting of approxi- mately 70 percent barium sulfate and 30 percent zinc sulfide It is widely used in the manufacture of white pigment and is also mixed with other pigments as a substitute for white lead
barium compounds Insoluble barium compounds (e g BaSO4) require an ashing procedure INTERFERENCES Ionization of barium in the flame is controlled by addition of sodium chloride to samples and standards Calcium at 0 1% gives a positive interference unless background correction is used OTHER METHODS This revises Method S198 [2]

It is found in chemical compounds Barium only occurs in one oxidation state +2 Most barium compounds are colorless The ones that dissolve in water or stomach acid are very toxic Barium sulfate is well known because it does not dissolve in water or acids Barium compounds are quite heavy Barium compounds put out a greenish flame when heated red-hot
Making a Precipitate of Barium Sulfate Using Exact Quantities of Reagents If two soluble ionic compounds such as barium chloride and ammonium sulfate are mixed the ions rearrange to form a precipitate of barium sulfate leaving ammonium and chloride ions in solution The reaction is BaCl 2 (aq) + (NH 4) 2 SO 4
