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.
Formula: Ba O 4 S: Molar mass: 233.38 g·mol −1: Barium sulfate suspension, often simply called barium, is a contrast agent used during X-rays. [1]
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 ...

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 determine if sulfate anions are present.
Molar mass: 169.39 g/mol Appearance ... Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [3]
Barium sulfite is the inorganic compound with the chemical formula BaSO 3. It is a white powder that finds few applications. It is an intermediate in the carbothermal reduction of barium sulfate to barium sulfide: [2] BaSO 4 + CO → BaSO 3 + CO 2
Strontium sulfate (SrSO 4) is the sulfate salt of strontium. It is a white crystalline powder and occurs in nature as the mineral celestine. It is poorly soluble in water to the extent of 1 part in 8,800. It is more soluble in dilute HCl and nitric acid and appreciably soluble in alkali chloride solutions (e.g. sodium chloride).
