Barium Sulfite

Barium sulfite is a chemical compound with the formula BaSO3. It consists of one barium ion (Ba2+) and one sulfite ion (SO32-). The molar mass of barium sulfite is 233.39 g/mol.

Barium sulfite is a white solid that is sparingly soluble in water. It can be prepared by reacting barium hydroxide (Ba(OH)2) with sulfur dioxide (SO2) in aqueous solution. The reaction proceeds as follows:

Ba(OH)2 + SO2 → BaSO3 + H2O

Barium sulfite has a crystal structure that belongs to the orthorhombic system. The lattice parameters are a = 9.870 Å, b = 6.855 Å, and c = 4.329 Å.

Barium sulfite has a wide range of applications. It is used as a reducing agent in organic chemistry, as a bleaching agent in papermaking, and as a preservative in food and wine. It is also used in the production of photographic papers and inks.

It should be noted that barium sulfite is toxic if ingested or inhaled. It can cause respiratory problems and can also lead to renal failure if absorbed into the bloodstream. Therefore, proper safety precautions should be taken when handling this compound.
