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 ...
Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide. [1] Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite. In a commercial sense, it is one of the most important barium compounds. [5]
Barium bromide can be prepared by treating barium sulfide or barium carbonate with hydrobromic acid: BaS + 2 HBr → BaBr 2 + H 2 S BaCO 3 + 2 HBr → BaBr 2 + CO 2 + H 2 O. Barium bromide crystallizes from concentrated aqueous solution in its dihydrate, BaBr 2 ·2H 2 O. Heating this dihydrate to 120 °C gives the anhydrous salt. [6]
