Calcium Sulphide- 1 Kg Packs

Calcium Sulphide is an inorganic compound composed of calcium and sulphur, belonging to the metal sulphide class of compounds. Its chemical formula is CaS, and its formula mass is approximately 72.14 g/mol. This compound is generally encountered as a white to pale yellow solid and exhibits characteristic sulphide chemistry. Calcium Sulphide is sensitive to moisture and can release hazardous hydrogen sulphide gas when it reacts with water or acids, making careful handling essential. It is relevant to inorganic chemistry studies, investigations of ionic compounds, solid-state materials research, and selected experiments involving sulphide reactions. Calcium Sulphide for laboratory use may be appropriate for specialised educational demonstrations, university investigations, and research procedures when the experimental requirements and safety controls are suitable. Its reactivity requires appropriate ventilation, moisture-controlled storage, and strict avoidance of incompatible materials. The supplied grade and specifications should be reviewed before selecting it for a particular laboratory application.

Frequently Asked Questions About Calcium Sulphide

What is Calcium Sulphide used for in laboratories?

Calcium Sulphide is used primarily in selected inorganic chemistry investigations, solid-state materials research, and studies of metal sulphide reactions. Its use requires appropriate facilities and trained personnel because contact with moisture or acids can release hazardous hydrogen sulphide gas. It is not suitable for unrestricted classroom demonstrations.

What is the chemical formula of Calcium Sulphide?

The chemical formula of Calcium Sulphide is CaS, and its empirical formula is also CaS. The compound consists of calcium and sulphide ions in a 1:1 ratio. Its formula mass is approximately 72.14 g/mol, making it distinguishable from other calcium-containing sulphur compounds.

What is the CAS number and molecular weight of Calcium Sulphide?

The CAS Registry Number for Calcium Sulphide is 20548-54-3. Its molecular or formula mass is approximately 72.14 g/mol. These identifiers correspond to calcium sulphide itself and should not be confused with those of calcium hydrogen sulphide, calcium sulphate, or calcium polysulphide.

Why must Calcium Sulphide be protected from moisture and acids?

Calcium Sulphide can react with moisture and acids to release hydrogen sulphide, a hazardous gas that can be toxic when inhaled. Some conditions may also create flammable gas or other reaction hazards. Keep the material dry, prevent contact with acids, and handle it only under appropriate controls specified by the Safety Data Sheet.

How should Calcium Sulphide be stored and handled safely?

Store Calcium Sulphide in a tightly closed, moisture-resistant compatible container in a dry, well-ventilated area, following the product-specific Safety Data Sheet. Avoid contact with acids, water, and incompatible oxidising agents. Use suitable protective equipment and appropriate ventilation, and prevent dust formation and release into the environment.

Storage Conditions for Calcium Sulphide

Store Calcium Sulphide in a tightly closed, compatible, moisture-resistant container in a cool, dry, well-ventilated area. Protect it from humidity and avoid contact with water, acids, and incompatible oxidising agents because hazardous reactions may occur. Keep it away from ignition sources where required by the applicable safety classification, and follow the current Safety Data Sheet for segregation and storage requirements.

Precautions for Handling Calcium Sulphide

Review the current Safety Data Sheet before use and handle Calcium Sulphide only in a suitably equipped laboratory with trained personnel. Wear appropriate chemical-resistant gloves, protective clothing, and eye protection, and use effective ventilation or a suitable fume hood. Avoid inhaling dust and prevent contact with moisture or acids. Do not discharge the material into drains or the environment. Follow established procedures for spills, hazardous gas risks, and chemical waste disposal.
