'''Barium sulfite''' is the [[barium]] [[Salt (chemistry)|salt]] of [[sulfurous acid]] with the [[chemical formula]] BaSO<sub>3</sub>. It is a white powder which is used in [[paper]] manufacturing. Like other [[barium]] compounds, it is toxic.<ref name="sci">barium sulfite. Answers.com. McGraw-Hill Dictionary of Scientific and Technical Terms, McGraw-Hill Companies, Inc., 2003. http://www.answers.com/topic/barium-sulfite, accessed July 19, 2009.</ref>
'''Barium sulfite''' is the [[inorganic compound]] with the [[chemical formula]] BaSO<sub>3</sub>. It is a white powder that finds few applications. It is an intermediate in the [[carbothermal reduction]] of [[barium sulfate]] to [[barium sulfide]]:<ref>{{Ullmann |doi=10.1002/14356007.a03_325.pub2|title=Barium and Barium Compounds|year=2007|last1=Kresse|first1=Robert|last2=Baudis|first2=Ulrich|last3=Jäger|first3=Paul|last4=Riechers|first4=H.
