Bismuth Sulphate, also spelled Bismuth Sulfate and known as Bismuth(III) Sulphate or Dibismuth Trisulphate, is an inorganic salt composed of bismuth and sulfate ions. Its chemical formula is Bi₂(SO₄)₃, and its molecular weight is approximately 706.15 g/mol. The compound is generally encountered as a white powder or solid and is poorly soluble in water. Bismuth Sulphate is relevant to inorganic chemistry, metal-salt investigations, and laboratory studies involving sulfate compounds and chemical reactions. It can be used in suitable analytical investigations involving the identification and behaviour of metal sulfates, as well as selected inorganic synthesis procedures. Its suitability for a specific experiment depends on the required grade, material specifications, and analytical method. This 250 g pack is intended for laboratory and research applications consistent with the stated product specifications and applicable chemical safety procedures.
