Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite. In a commercial sense, it is one of the most important barium compounds. [5]

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 is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2] BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium ...
Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its aqueous solution, if clear, is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water.
Barium oxide from metalic barium readly forms from its exothermic oxidation with dioxygen in air: 2 Ba(s) + O 2 (g) → 2 BaO(s). It's most commonly made by heating barium carbonate at temperatures of 1000–1450 °C. BaCO 3 (s) → BaO(s) + CO 2 (g) Likewise, it is often formed through the thermal decomposition of other barium salts, [6] like ...
Witherite is a barium carbonate mineral, Ba C O 3, in the aragonite group. [2] Witherite crystallizes in the orthorhombic system and virtually always is twinned. [2] The mineral is colorless, milky-white, grey, pale-yellow, green, to pale-brown. The specific gravity is 4.3, which is high for a translucent mineral. [2]
