Barium sulfite is the inorganic compound with the chemical formula BaSO 3. It is a white powder that finds few applications. It is a white powder that finds few applications. It is an intermediate in the carbothermal reduction of barium sulfate to barium sulfide : [ 2 ]
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

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 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 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]
Barium nitrate is the inorganic compound with the chemical formula Ba(NO 3) 2. It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. [4]
