Barium sulfite
Encyclopedia
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.
It may be formed by the action of sulfur dioxide
on barium oxide
or barium hydroxide
.
Barium
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Barium is never found in nature in its pure form due to its reactivity with air. Its oxide is historically known as baryta but it reacts with...
