Barium Sulfate Formula

Barium sulfate formula is  BaSO₄. It is an inorganic compound. This odorless, white crystalline solid does not dissolve in water. It is naturally found in the mineral barite, which serves as the primary source for barium and its derived materials for commercial purposes.

Barium is an element denoted by the symbol Ba and possesses an atomic number of 56. This soft, silvery alkaline earth metal is divalent in nature and holds the sixth position in group 2 of the periodic table. In its natural state, it is never found as a standalone element due to its exceptionally high chemical reactivity. 

Barium is typically encountered in combination with other compounds such as sulfur, carbon, or oxygen. It is notably lightweight, boasting a density that is merely half that of iron. In the presence of oxygen, barium undergoes oxidation and reacts vigorously with water, yielding hydroxide and releasing hydrogen gas. When it comes into contact with virtually all non-metals, barium forms intricate chemical compounds that are often toxic in nature.

Barium Sulfate Formula

Barium sulfate formula is  BaSO₄. Barium sulfate is a white crystalline inorganic solid known for its lack of odor and insolubility in water. It occurs naturally in the mineral barite, which serves as the primary source for commercial barium and barium-related products.

Its primary applications capitalize on its white, opaque appearance and high density. Moreover, it is non-toxic and finds use in medical contexts. In the oil and gas industry, it is frequently used to create high-density drilling fluids, thereby keeping boreholes clear of rocks. Barium sulfate can also be produced by reducing barium sulfide with carbon. 

Barium Sulfate Formula Structure

Barium sulfate formula is  BaSO₄. Barium sulfate is composed of one barium cation (Ba²⁺) and one sulfate anion (SO₄²⁻). The sulfate ion consists of four oxygen atoms bonded to sulfur. As a result, the molecular or chemical formula of Barium Sulfate is BaSO₄. This compound has a molecular mass of 233.38 grams per mole and exhibits an orthorhombic crystalline structure with a dipole moment of zero. Barium sulfate is a chemical compound composed of barium, a soft and silvery metal, combined with sulfur and oxygen. It occurs naturally in the mineral barite, existing as a salt of barium sulfate.
