Calcium Sulpahte Anhydrous- 1 Kg Packs

Calcium Sulphate Anhydrous is an inorganic calcium salt with the chemical formula CaSO₄, classified as a sulphate compound. Unlike hydrated forms such as calcium sulphate dihydrate, anhydrous calcium sulphate contains no water of crystallisation. It is generally encountered as a white or nearly white solid and is relevant to laboratory studies involving inorganic salts, solubility, precipitation reactions, and the chemistry of calcium and sulphate ions. Its limited solubility in water makes it useful in selected qualitative and quantitative chemistry experiments, while its defined composition supports investigations of hydrate formation and water uptake under appropriate conditions. Calcium Sulphate Anhydrous for laboratory use may be suitable for educational practicals, analytical procedures, and research involving inorganic materials, subject to the specified grade and experimental requirements. Proper storage in a tightly closed container helps minimise unwanted moisture uptake and maintain the intended anhydrous form.

Frequently Asked Questions About Calcium Sulphate Anhydrous

What is Calcium Sulphate Anhydrous used for in laboratories?

Calcium Sulphate Anhydrous is used in inorganic chemistry experiments, solubility investigations, studies of calcium and sulphate compounds, and selected materials research. Certain forms can also act as drying agents because they absorb water. Its suitability for drying or analytical work depends on the specific form, required performance, and experimental method.

What is the chemical formula of Calcium Sulphate Anhydrous?

The chemical formula is CaSO₄, and its empirical formula is also CaSO₄ because the elemental ratio is already in its simplest whole-number form. The anhydrous compound contains no water of crystallisation, unlike calcium sulphate dihydrate, CaSO₄·2H₂O.

What are the CAS number and molecular weight of Calcium Sulphate Anhydrous?

The CAS Registry Number is 7778-18-9, and its formula mass is approximately 136.14 g/mol. These values apply to anhydrous calcium sulphate. Calcium sulphate hydrates have different formula masses because their chemical compositions include water molecules.

Can Calcium Sulphate Anhydrous be used as a drying agent?

Some forms of anhydrous calcium sulphate can absorb moisture and are used as laboratory drying agents. However, the moisture-absorbing capacity depends on the material’s preparation and physical form. Confirm that the supplied product is appropriate for the intended drying procedure before using it in analytical or research work.

How should Calcium Sulphate Anhydrous be stored and handled?

Keep the material in a tightly closed, compatible container in a dry, well-ventilated storage area. Avoid generating dust and prevent contact with the eyes and prolonged skin exposure. Wear appropriate laboratory protective equipment and consult the current Safety Data Sheet for specific handling, incompatibility, spill response, and disposal requirements.

Storage Conditions for Calcium Sulphate Anhydrous

Store Calcium Sulphate Anhydrous in a tightly closed, compatible container in a cool, dry, well-ventilated area. Protect moisture-sensitive grades from humidity to preserve the intended anhydrous composition and any moisture-absorbing properties. Keep the container clearly labelled and avoid contamination. Follow the supplier’s storage guidance and the current Safety Data Sheet, particularly when the material is intended for use as a laboratory drying agent.

Precautions for Handling Calcium Sulphate Anhydrous

Review the current Safety Data Sheet before use. Wear suitable safety goggles, laboratory clothing, and gloves, and avoid inhaling airborne dust or allowing the powder to contact the eyes. Use appropriate ventilation when weighing or transferring dusty material. Keep containers closed when not in use, clean spills using suitable laboratory procedures, and dispose of waste according to institutional requirements and applicable regulations.
