  2. Barium carbonate - Wikipedia

    en.wikipedia.org/wiki/Barium_carbonate

    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

  6. Barium carbide - Wikipedia

    en.wikipedia.org/wiki/Barium_carbide

    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.

  7. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.
