Barium carbonate is made commercially from barium sulfide by treatment with sodium carbonate at 60 to 70 °C (soda ash method) or, more commonly carbon dioxide at 40 to 90 °C: In the soda ash process, an aqueous solution of barium sulfide is treated with sodium carbonate: [5] BaS + H 2 O + CO 2 → BaCO 3 + H 2 S

When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
Barium carbide can be synthesized as an impure compound by reducing barium carbonate powder with metallic magnesium in the presence of carbon. [3] Barium carbide can also be made by reducing carbon dioxide with hot barium metal at 600°C. [4] These methods are used because of their high yield, and because the carbide is used to make acetylene.
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.
