Barium Oxide – 500 gram Packs

Barium Oxide is an inorganic compound formed from barium and oxygen, with the chemical formula BaO. Also known as barium monoxide, it belongs to the alkaline earth metal oxide family and exhibits strongly basic chemical behaviour. Barium Oxide has a molecular weight of 153.33 g/mol and is commonly described as a white to yellowish solid. It reacts with water to form barium hydroxide and readily interacts with moisture and carbon dioxide in the air, making controlled storage important. Barium Oxide Laboratory Reagent is relevant to selected inorganic chemistry experiments, investigations of metal oxides, and research involving solid-state reactions and chemical reactivity. Its suitability for educational, analytical, or research procedures depends on the method and required reagent specifications. As a corrosive and toxic chemical, it requires trained handling, suitable protective equipment, moisture control, and strict adherence to laboratory safety and hazardous-waste procedures.

Frequently Asked Questions About Barium Oxide

What is Barium Oxide used for in laboratories?

Barium Oxide is used in selected inorganic chemistry investigations involving metal oxides, basic oxide reactions, and the preparation or study of barium-containing materials. It may also be relevant to specialised materials research. Its corrosive and toxic properties require appropriate facilities, trained personnel, and a documented risk assessment before use.

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

The molecular formula of Barium Oxide is BaO, and its molecular weight is approximately 153.33 g/mol. Its empirical formula is also BaO because the simplest whole-number ratio of barium to oxygen is 1:1. These values refer to barium monoxide, not barium peroxide, which has a different formula and molecular weight.

What is the CAS number of Barium Oxide?

The CAS Registry Number for Barium Oxide is 1304-28-5. This identifier distinguishes barium monoxide from related substances such as barium peroxide and barium hydroxide. Confirming the CAS number helps laboratories select the correct chemical during procurement, inventory management, and safety documentation review.

Why must Barium Oxide be protected from moisture?

Barium Oxide reacts with water to form barium hydroxide and can react with carbon dioxide to form barium carbonate. Exposure to humid air can therefore alter its chemical composition and properties. Keeping the material tightly sealed under suitable dry storage conditions helps limit unwanted reactions and contamination.

How should Barium Oxide be handled safely?

Barium Oxide is corrosive and toxic if swallowed, and its dust can be harmful if inhaled. Review the current Safety Data Sheet, wear suitable gloves, protective clothing, and eye protection, and use appropriate ventilation. Prevent contact with water during handling unless required by a controlled procedure, and follow approved spill-response and hazardous-waste disposal practices.

Storage Conditions for Barium Oxide

Store Barium Oxide in a tightly closed, moisture-resistant, compatible container in a cool, dry, well-ventilated area. Protect it from humid air and carbon dioxide, and segregate it from water, acids, and other incompatible substances. Keep the container clearly labelled and securely stored with access restricted to trained personnel. Follow the current Safety Data Sheet for specific storage and segregation requirements.

Precautions for Handling Barium Oxide

Review the current Safety Data Sheet before use. Wear chemical-resistant gloves, protective clothing, and suitable eye and face protection. Avoid generating or inhaling dust and prevent contact with skin and eyes. Handle the material in appropriate ventilation and avoid uncontrolled contact with water or incompatible chemicals. Because Barium Oxide is corrosive and toxic, ensure that trained personnel manage spills, emergency procedures, and hazardous-waste disposal in accordance with institutional requirements.
