Barium Sulphate – 500 gram Packs

Barium Sulphate is an inorganic compound consisting of barium and sulphate ions, with the chemical formula BaSO₄. Also known as barium sulfate, barite, or barium sulphate, it is characterised by its white powder appearance, high density, and extremely low solubility in water. With a molecular weight of approximately 233.39 g/mol, Barium Sulphate is relevant to inorganic chemistry, precipitation reactions, gravimetric analysis, and studies of sparingly soluble salts. Its chemical stability and limited solubility make it useful in selected analytical procedures and research involving sulphate determination and inorganic materials. Barium Sulphate Laboratory Reagent may be suitable for educational, analytical, and research applications when its specifications meet the requirements of the intended method. Although it is substantially less soluble than many other barium salts, airborne dust should still be controlled during handling. Appropriate laboratory hygiene, protective equipment, and responsible waste management are essential.

Frequently Asked Questions About Barium Sulphate

What is Barium Sulphate used for in laboratories?

Barium Sulphate is used in inorganic chemistry practicals, precipitation studies, and selected gravimetric analytical procedures involving sulphate determination. Its low water solubility makes it useful where formation of a sparingly soluble solid is required. Suitability for quantitative work depends on the analytical method and the reagent specifications needed.

What are the molecular formula and molecular weight of Barium Sulphate?

The molecular formula of Barium Sulphate is BaSO₄, and its formula mass is approximately 233.39 g/mol. Its empirical formula is also BaSO₄ because the ratio of barium, sulphur, and oxygen atoms cannot be reduced further. These values refer to anhydrous Barium Sulphate.

What is the CAS number of Barium Sulphate?

The CAS Registry Number for Barium Sulphate is 7727-43-7. This identifier helps distinguish the compound from other barium salts, including more soluble barium compounds. It is useful for chemical procurement, laboratory inventory records, and checking relevant technical and safety information.

Is Barium Sulphate soluble in water?

Barium Sulphate is practically insoluble in water because of its stable ionic crystal structure and very low solubility product. This property is important in precipitation reactions and gravimetric analysis. Its solubility behaviour can differ in specialised chemical media, so analytical procedures should follow the conditions specified by the method.

How should Barium Sulphate be stored and handled safely?

Store Barium Sulphate in a tightly closed, clearly labelled container in a dry, well-ventilated area. Avoid generating or inhaling fine dust, use suitable gloves and eye protection, and maintain good laboratory hygiene. Follow the current Safety Data Sheet and institutional procedures for spill management, chemical waste disposal, and exposure prevention.

Storage Conditions for Barium Sulphate

Store Barium Sulphate in a tightly closed, compatible, clearly labelled container in a cool, dry, well-ventilated area. Protect the powder from contamination and moisture, and avoid storage near incompatible materials such as aluminium powder under conditions that could promote hazardous reactions. Restrict access to authorised personnel and prevent dust or waste from entering drains or the environment.

Precautions for Handling Barium Sulphate

Review the current Safety Data Sheet before use. Wear suitable gloves, protective clothing, and safety goggles, and minimise the generation and inhalation of airborne dust. Use appropriate ventilation when handling fine powder and maintain good laboratory hygiene. Avoid uncontrolled mixing with incompatible substances, clean spills using approved dust-control procedures, and dispose of collected material according to institutional and applicable hazardous-waste requirements.
