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 azide – Ba(N 3) 2 [84] Barium bromide – BaBr 2; Barium carbonate – BaCO 3 [85] Barium chlorate – Ba(ClO 3) 2 [86] Barium chloride – BaCl 2 [87] Barium chromate – BaCrO 4 [88] Barium ferrate – BaFeO 4; Barium ferrite – BaFe 12 O 19 [89] Barium fluoride – BaF 2 [90] Barium hydroxide – Ba(OH) 2 [91] [92] Barium iodide ...
The abundance of barium is 0.0425% in the Earth's crust and 13 μg/L in sea water. The primary commercial source of barium is baryte (also called barytes or heavy spar), a barium sulfate mineral. [9]: 5 with deposits in many parts of the world. Another commercial source, far less important than baryte, is witherite, barium carbonate. The main ...
The second step requires reaction between barium sulfide and hydrogen chloride: BaS + 2 HCl → BaCl 2 + H 2 S. or between barium sulfide and calcium chloride: BaS + CaCl 2 → CaS + BaCl 2 [2] In place of HCl, chlorine can be used. [7] Barium chloride is extracted out from the mixture with water.

The electrically neutral hydrogen atom contains a nucleus of a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1] In everyday life on Earth, isolated hydrogen atoms (called "atomic hydrogen") are ...
The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
The ion/molecule/atom surrounding the central ion/molecule/atom is called a ligand. This number is determined somewhat differently for molecules than for crystals. For molecules and polyatomic ions the coordination number of an atom is determined by simply counting the other atoms to which it is bonded (by either single or multiple bonds). [1]
