Barium nitrate Barium nitrate Barium nitrate is the inorganic compound with the chemical formula Ba(NO). 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. Barium nitrate is manufactured by two processes that start with the main source material for barium, the carbonate. The first involves dissolving barium carbonate in nitric acid, allowing any iron impurities to precipitate, then filtered, evaporated, and crystallized. The second requires combining barium sulfide with nitric acid. It occurs naturally as the very rare mineral "nitrobarite". At elevated temperatures, barium
Sodium chlorate Sodium chlorate Sodium chlorate is an inorganic compound with the chemical formula NaClO. It is a white crystalline powder that is readily soluble in water. It is hygroscopic. It decomposes above 300 °C to release oxygen and leave sodium chloride. Several hundred million tons are produced annually, mainly for applications in bleaching paper. Industrially, sodium chlorate is produced by the electrolysis of a hot sodium chloride solution: This reaction progresses in heat (at least 70 degrees Celsius), and controlled pH. In lower temperature or with high pH another reaction progresses: 2 NaCl + HO → NaClO + NaCl + H
