Copper Sulphite – 500 gram Packs

Copper Sulphite, also described as a copper sulphite compound, is an inorganic material containing copper and the sulphite ion (SO₃²⁻). Unlike copper sulphide, which contains sulphide ions, copper sulphite incorporates sulphur bonded to oxygen. Copper sulphite chemistry includes mixed-valence compounds containing both copper(I) and copper(II), notably Chevreul’s salt, which commonly occurs as a dihydrate with the formula Cu₃(SO₃)₂·2H₂O. Such compounds are relevant to inorganic synthesis, precipitation chemistry, and investigations of copper oxidation states. Their properties depend on the exact composition and hydration state, making correct identification important for laboratory work. Copper sulphite materials may be studied in supervised educational experiments and specialised research involving inorganic salts and solid-state chemistry. This 500 gram pack is intended for laboratory applications only after the supplied chemical form has been confirmed against the product specification.

Key Features of Copper Sulphite

• Sulphite-based inorganic chemistry: Contains sulphite species, which differ chemically from sulphide and sulphate ions.
• Multiple copper oxidation states: Certain copper sulphite compounds contain both copper(I) and copper(II), making them relevant to oxidation-state studies.
• Compound-specific composition: Formula, hydration state, appearance, and formula mass depend on the exact copper sulphite compound.
• Inorganic reaction relevance: Copper sulphite compounds are associated with precipitation and selected inorganic synthesis investigations.
• Research applications: Identified copper sulphite phases may be investigated in solid-state chemistry and studies of copper-containing materials.

Laboratory Applications of Copper Sulphite

• Inorganic chemistry investigations: Supports studies of sulphite compounds and the chemical behaviour of copper-containing inorganic materials once the exact compound is identified.
• Precipitation chemistry: Relevant to investigations of precipitate formation involving copper ions and sulphite species under suitable controlled conditions.
• Oxidation-state studies: Mixed-valence copper sulphite compounds can be used in appropriate investigations of copper(I) and copper(II) chemistry.
• Inorganic synthesis research: An identified copper sulphite compound may serve as a starting material in selected preparations of copper-containing materials.
• Solid-state research: Characterised copper sulphite phases may be investigated for their structural and chemical properties in specialised research settings.

Why Choose Lab Wale to Buy Copper Sulphite

Lab Wale provides a sourcing option for laboratory chemicals and scientific supplies used by educational institutions, universities, research centres, and laboratory professionals. For Copper Sulphite, confirming the exact chemical identity is especially important because different copper sulphite compositions and hydrated forms have different specifications. Before selecting the 500 gram pack for a particular procedure, verify the formula, CAS number, stated grade, and available technical and safety information. Matching the reagent to the intended application supports accurate laboratory planning and responsible chemical handling.

Frequently Asked Questions About Copper Sulphite

What is Copper Sulphite used for in laboratories?

Copper sulphite compounds are relevant to inorganic synthesis, precipitation chemistry, and investigations of copper oxidation states. The appropriate applications depend on the exact compound and its hydration state. Confirm the chemical identity before using the material in educational experiments, analytical procedures, or research work.

What is the chemical formula of Copper Sulphite?

The formula depends on the specific copper sulphite compound. Chevreul’s salt, a mixed copper(I,II) sulphite dihydrate, has the formula Cu₃(SO₃)₂·2H₂O. Other copper sulphite compositions exist, so this formula should not be assigned to an unspecified product without confirming its identity.

What is the CAS number of Copper Sulphite?

There is no single CAS number that should be assigned to every compound described as copper sulphite. Chevreul’s salt dihydrate is identified by CAS number 13814-81-8, while anhydrous mixed copper(I,II) sulphite is associated with CAS number 15293-86-4. The correct identifier depends on the actual supplied form.

What is the difference between Copper Sulphite and Copper Sulphide?

Copper sulphite contains the sulphite ion, SO₃²⁻, which includes sulphur and oxygen. Copper sulphide contains sulphide ions and no oxygen in the anion. These compounds have different chemical compositions, properties, and applications, so they must not be substituted for one another without checking the experimental requirements.

How should Copper Sulphite be stored and handled safely?

Store the identified compound in a compatible, tightly closed container under the conditions specified in its applicable Safety Data Sheet. Avoid generating dust, wear suitable gloves and eye protection, and use appropriate ventilation. Because sulphite compounds can behave differently under acidic conditions, follow compound-specific handling procedures and avoid unapproved mixing.

Storage Conditions for Copper Sulphite

Store Copper Sulphite in a compatible, tightly closed container in a cool, dry, well-ventilated location, following the requirements for the exact compound. Protect the material from contamination and avoid contact with incompatible substances. Since hydration state and chemical stability may vary between copper sulphite compounds, use the applicable Safety Data Sheet to determine any additional storage requirements.

Precautions for Handling Copper Sulphite

Review the applicable Safety Data Sheet before handling the material. Wear suitable protective gloves, safety goggles, and laboratory clothing, and avoid inhaling dust or allowing contact with the eyes and skin. Do not mix the compound with acids or other reagents unless the procedure specifically permits it and appropriate controls are in place. Use suitable ventilation, follow institutional spill-response procedures, and dispose of copper-containing waste through an approved chemical-waste route.
