Copper Sulphide – 500 gram Packs

Copper Sulphide, commonly identified as Copper(II) Sulphide or cupric sulphide, is an inorganic compound composed of copper and sulphur, with the chemical formula CuS. It is generally encountered as a black solid and is associated with the mineral covellite. Copper Sulphide is practically insoluble in water and exhibits electrical and electronic properties that make copper sulphide materials relevant to solid-state chemistry and materials science. In laboratory settings, it is used in selected inorganic synthesis procedures, investigations of metal sulphide formation, and research involving copper-based semiconductor materials. It can also support supervised educational experiments exploring precipitation reactions and the chemical behaviour of metal sulphides. Its suitability for analytical or research procedures depends on the required chemical form, reagent grade, and experimental specifications. This 500 gram pack is intended for laboratory use with appropriate handling, storage, and environmental precautions.

Frequently Asked Questions About Copper Sulphide

What is Copper Sulphide used for in laboratories?

Copper Sulphide is used in selected inorganic chemistry investigations, metal sulphide synthesis, solid-state research, and studies of copper-based semiconductor materials. It can support research into the structural and electronic properties of inorganic solids. Its suitability depends on the specific compound, material requirements, and experimental procedure.

What is the chemical formula of Copper Sulphide?

The formula of Copper(II) Sulphide is CuS, and its empirical formula is also CuS because the copper-to-sulphur atomic ratio cannot be simplified further. Its formula mass is approximately 95.61 g/mol. Copper(I) Sulphide, Cu₂S, is a different compound with a different formula mass and chemical identity.

What is the CAS number of Copper Sulphide?

The CAS Registry Number associated with Copper(II) Sulphide, CuS, is 1317-40-4. Copper(I) Sulphide, Cu₂S, is a distinct compound with different identifiers. Checking the CAS number is important when ordering chemicals for research, synthesis, or laboratory experiments that require a specific copper sulphide composition.

Is Copper Sulphide soluble in water?

Copper(II) Sulphide is practically insoluble in water under ordinary conditions. This property is relevant to metal sulphide precipitation and solid-state investigations. Its behaviour can differ under specialised chemical conditions, so the solvent, reaction environment, and intended analytical method should be considered when planning laboratory work.

How should Copper Sulphide be stored and handled safely?

Store Copper Sulphide in a tightly closed, compatible container in a cool, dry, well-ventilated area. Avoid generating or inhaling dust and prevent contact with the eyes and skin. Use suitable gloves, protective eyewear, and appropriate ventilation. Follow the applicable Safety Data Sheet and prevent the material from entering drains or the environment.

Storage Conditions for Copper Sulphide

Store Copper Sulphide in a tightly closed, compatible container in a cool, dry, well-ventilated location. Protect the material from contamination and unnecessary exposure to moisture. Keep it segregated from incompatible substances in accordance with the applicable Safety Data Sheet and institutional chemical-storage procedures. Maintain clear container labelling and follow supplier-specific storage recommendations for the supplied product.

Precautions for Handling Copper Sulphide

Review the current Safety Data Sheet before handling Copper Sulphide. Wear suitable protective gloves, safety goggles, and laboratory clothing. Avoid inhaling dust and prevent contact with the eyes and skin. Use appropriate ventilation during weighing and transfer operations. Prevent spills from reaching drains, soil, or waterways, and collect residues using approved chemical-waste procedures. Follow institutional spill-response requirements and ensure suitable supervision during educational laboratory activities.
