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.

Barium sulfate – BaSO 4 [103] Barium sulfide – BaS [104] Barium titanate – BaTiO 3 [105] Barium thiocyanate – Ba(SCN) 2 [106] Be. Beryllium borohydride – Be ...
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 ...
Solutions of barium bromide reacts with the sulfate salts to produce a solid precipitate of barium sulfate. BaBr 2 + SO 2− 4 → BaSO 4 + 2 Br −. Similar reactions occur with oxalic acid, hydrofluoric acid, and phosphoric acid, giving solid precipitates of barium oxalate, fluoride, and phosphate, respectively.
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. [8] Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate. Inhalation may also cause irritation to the respiratory tract.
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. Alternatively, barium ...
Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [ 3 ] It is an important precursor to other barium compounds including barium carbonate and the pigment lithopone , ZnS/BaSO 4 . [ 4 ]
