Barium sulfite is the barium salt of sulfurous acid with the chemical formula BaSO3. It is a white powder which is used in paper manufacturing. Like other barium compounds, it is toxic.[2]
It may be formed by the action of sulfur dioxide on barium oxide or barium hydroxide. It can also be formed by treating barium with sulfurous acid.
