  1. Definition of Ba
    Ba, also known as Bari, is a chemical element with the symbol Ba and the atomic number 56. Bari is known in English as Barium. Ba has an atomic mass of 137.327 u and an atomic weight of about 137.33. A Ba molecule is made up of a single atom of Ba. Ba ions are also formed from a single atom of Ba but lose two outermost electrons, possessing a 2+ charge.
  2. Properties of Ba
    At room temperature, Ba is in a solid state, has a silver-white color, and does not have a special smell. The chemical properties of Ba are quite unique, this element reacts vigorously with water to create hydrogen and Ba(OH)2.
  3. Common Chemical Reactions of Ba
    Ba is capable of reacting with metals, acids, non-metals, and salts. For example, Ba can react with O2 to form BaO, with HCl to form BaCl2 and H2, with N2 to form Ba3N2, with NaCl to form BaCl2 and Na.
    Ba + O2 -> BaO
    Ba + 2HCl -> BaCl2 + H2
    3 Ba + N2 -> Ba3N2
    Ba + 2NaCl -> BaCl2 + 2Na
    A characteristic reaction to identify Ba is its reaction with the SO4 2- radical to form an insoluble salt in acids, bases, salts…
    Ba + H2SO4 -> BaSO4 + H2
    BaCl2 + Na2SO4 -> 2NaCl + BaSO4
    Ba(OH)2 + Fe2(SO4)3 -> 2Fe(OH)3 + 3BaSO4
  4. Preparation of Ba
    In the laboratory, Ba is typically prepared from barite ore (BaSO4) through a reaction with coal. On an industrial scale, Ba is produced from barite ore by roasting it with coal in a melting furnace at very high temperatures.
