Production and representation

, Barium can be obtained by the reaction of sodium sulfite with a solution of barium chloride or barium carbonate.

Properties

Physical Properties

Barium sulfite is a white odorless non-flammable solid that is very slightly soluble in water. In acids it is readily soluble. He has a monoclinic crystal system with a unit cell size of 664.7 x 548.3 x 464.5 A and an angle of 106.3 °. Also, a triclinic form is known.

Chemical Properties

Barium sulfite can be oxidized with hydrogen peroxide quantitatively with barium sulfate.

Heating a solution of barium sulfite in sulfurous acid decomposes it with the formation of barium sulfate and a polythionate.

When annealing the absence of air to barium sulfite decomposes to barium sulfate and barium.
