Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [ 3 ] It is an important precursor to other barium compounds including barium carbonate and the pigment lithopone , ZnS/BaSO 4 . [ 4 ]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

[9]: 7 It is then reduced by carbon to barium sulfide: [9]: 6 BaSO 4 + 2 C → BaS + 2 CO 2. The water-soluble barium sulfide is the starting point for other compounds: treating BaS with oxygen produces the sulfate, with nitric acid the nitrate, with aqueous carbon dioxide the carbonate, and so on.

Barium sulfite is the inorganic compound with the chemical formula BaSO 3. It is a white powder that finds few applications. It is a white powder that finds few applications. It is an intermediate in the carbothermal reduction of barium sulfate to barium sulfide : [ 2 ]
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide: BaS + ZnSO 4 → ZnS·BaSO 4. This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO 4.
