Barium Sulphite – 500 gram Packs

Barium Sulphite is an inorganic salt composed of barium cations and sulphite anions, represented by the chemical formula BaSO₃. Also known as barium sulfite or barium(II) sulphite, it belongs to the metal sulphite family and is characterised by its low solubility in water. Anhydrous Barium Sulphite has a formula mass of approximately 217.39 g/mol and generally occurs as a white solid. Its chemical properties make it relevant to inorganic chemistry, precipitation reactions, solubility equilibrium studies, and investigations involving sulphur-containing compounds. Barium Sulphite Laboratory Reagent may be considered for appropriate educational, analytical, and research procedures when its specifications match the requirements of the intended method. Because it contains barium, careful handling is necessary to minimise dust exposure and prevent accidental ingestion. Suitable personal protective equipment, controlled laboratory practices, and responsible chemical waste management are essential for safe use.

Frequently Asked Questions About Barium Sulphite

What is Barium Sulphite used for in laboratories?

Barium Sulphite is relevant to inorganic chemistry experiments, precipitation studies, solubility investigations, and selected research involving sulphite compounds. Its suitability depends on the experimental method and required specifications. Appropriate exposure controls and hazardous-waste management are necessary because barium compounds can present health risks.

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

The molecular formula of anhydrous Barium Sulphite is BaSO₃, and its formula mass is approximately 217.39 g/mol. Its empirical formula is also BaSO₃ because the ratio of barium, sulphur, and oxygen atoms cannot be reduced further.

What is the CAS number of Barium Sulphite?

The CAS Registry Number commonly associated with Barium Sulphite is 7787-39-5. This identifier helps distinguish the compound from barium sulphate and other sulphur-containing barium salts during procurement, inventory management, and safety documentation review.

Is Barium Sulphite soluble in water?

Barium Sulphite has low solubility in water and can dissolve in suitable acidic media. This behaviour makes it relevant to precipitation and solubility equilibrium investigations. Its behaviour in a particular procedure depends on factors such as acidity, temperature, and the presence of other dissolved ions.

How should Barium Sulphite be stored and handled safely?

Store Barium Sulphite in a tightly closed, compatible, clearly labelled container in a dry, well-ventilated area. Avoid generating or inhaling dust, wear suitable gloves and eye protection, and prevent accidental ingestion. Follow the current Safety Data Sheet and institutional procedures for chemical segregation, spill response, and hazardous-waste disposal.

Storage Conditions for Barium Sulphite

Store Barium Sulphite in a tightly closed, compatible, clearly labelled container in a cool, dry, well-ventilated area. Protect it from contamination and excessive moisture, and segregate it from incompatible chemicals according to the applicable Safety Data Sheet. Restrict access to authorised laboratory personnel and prevent dust, spills, or chemical waste from entering drains or the environment.

Precautions for Handling Barium Sulphite

Review the current Safety Data Sheet before use. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and avoid inhaling dust or allowing the powder to contact skin and eyes. Use appropriate ventilation when dust may be generated, maintain good laboratory hygiene, and avoid uncontrolled mixing with incompatible substances. Follow approved procedures for spill response and hazardous-waste disposal. Educational use requires appropriate supervision and a documented risk assessment.
