Barium Sulphite- 1 Kg Packs

Barium Sulphite is an inorganic salt composed of barium cations and sulphite anions, with the chemical formula BaSO₃. Also known as barium sulfite or barium(II) sulphite, it belongs to the family of metal sulphites and is generally encountered as a white crystalline powder. It has a formula mass of approximately 217.39 g/mol and exhibits low solubility in water while dissolving in suitable dilute acids. These properties make Barium Sulphite relevant to inorganic chemistry, precipitation reactions, solubility studies, and investigations of sulphur-containing compounds. Barium Sulphite Laboratory Reagent may be suitable for selected educational, analytical, and research procedures when its specifications meet the requirements of the intended method. As a barium compound, it requires careful handling to minimise dust exposure and prevent accidental ingestion. Appropriate protective equipment, suitable storage, and responsible chemical waste management are essential for laboratory 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. Laboratory personnel should consider the toxicity associated with barium compounds and follow appropriate exposure controls and hazardous-waste management procedures.

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

The molecular formula of 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. These values refer to anhydrous Barium Sulphite.

What is the CAS number of Barium Sulphite?

The CAS Registry Number for 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 dissolves in suitable dilute acids. This behaviour makes it relevant to precipitation reactions and solubility equilibrium investigations. Experimental results depend on conditions 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, use suitable gloves and eye protection, and prevent accidental ingestion. Follow the current Safety Data Sheet and institutional procedures for spill response, chemical segregation, 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 in accordance with the applicable Safety Data Sheet. Restrict access to authorised laboratory personnel and prevent dust 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 and avoid uncontrolled mixing with incompatible substances. Maintain good laboratory hygiene and follow approved procedures for spill response and hazardous-waste disposal. Educational use requires suitable supervision and a documented risk assessment.
