Product Overview
Copper(II) Sulphate Pentahydrate is an inorganic salt composed of copper ions, sulphate ions and five molecules of water of crystallisation. Its characteristic blue colour makes it useful in teaching experiments involving hydrated salts, crystal formation and chemical change.
The Merck EMSURE® grade is intended for demanding analytical work where a defined assay and controlled impurity limits are important. The manufacturer provides specifications for insoluble matter, chloride and selected cation impurities, including calcium, iron, potassium, sodium, nickel, lead and zinc.
When dissolved in water, the product provides copper(II) and sulphate ions for approved laboratory reactions. Its blue solution may be used in controlled demonstrations of ion behaviour, metal displacement, electrolysis and selected complex-formation reactions.
This product is a laboratory chemical and should not be confused with agricultural, electroplating, industrial, feed, veterinary or household grades. Suitability for food, pharmaceutical, medical, agricultural or other regulated applications requires the correct approved grade and separate documentation.
Main Applications
Hydrated-Salt and Water-of-Crystallisation Experiments
Copper Sulphate Pentahydrate may be used in supervised practical work to demonstrate hydrated salts and water of crystallisation. Controlled heating changes the blue hydrated material as water is removed. The procedure must use small quantities, suitable heat-resistant equipment and direct supervision.
Crystallisation and Recrystallisation Studies
The product may be dissolved in water and used in approved crystal-growing or recrystallisation experiments. Students can observe how concentration, cooling and evaporation affect crystal formation. Prepared crystals must remain laboratory chemicals and must not be handled as decorative or household items.
Laboratory Solution Preparation
Qualified personnel may prepare method-specific Copper Sulphate solutions for teaching or analytical work. The required mass, concentration and final volume must be calculated from the pentahydrate formula and the approved laboratory method.
Metal-Displacement Demonstrations
Copper Sulphate solution may be used in supervised demonstrations involving a more reactive metal, such as iron or zinc, where the approved method illustrates metal displacement and redox behaviour. Waste metals and copper-containing solutions require controlled collection.
Electrolysis and Electrochemistry Experiments
In properly designed college or university practicals, Copper Sulphate solution may support demonstrations of electrolysis, electrode reactions or copper deposition. Electrical equipment, electrodes, concentration and waste handling must follow the approved experiment.
Qualitative Tests for Copper(II) Ions
The reagent may provide copper(II) ions for selected qualitative-analysis reactions, including approved precipitation or complex-formation demonstrations. Additional reagents may carry separate hazards and must be covered by the experiment-specific risk assessment.
Qualitative Tests for Sulphate Ions
Copper Sulphate may be used as a sulphate-ion source in controlled qualitative demonstrations. Traditional sulphate tests may involve hazardous barium compounds, so reagent preparation and waste collection must be managed by trained personnel.
Preparation of Selected Analytical Reagents
The product may be required in selected analytical reagent formulations, including method-specific copper solutions. Preparation must follow a validated standard rather than an improvised general recipe, and the prepared solution should be labelled with its concentration, date and hazards.
Research and Quality-Control Work
Research and quality-control laboratories may use EMSURE® Copper(II) Sulfate Pentahydrate in validated methods where its assay and impurity specification are suitable. Batch COA review is recommended for critical work.

Clear visual teaching value: The blue crystals and solutions help demonstrate hydration, crystallisation and chemical change.
Multiple laboratory applications: It can support approved solution preparation, ion reactions, displacement, electrochemistry and qualitative analysis.
Water-soluble reagent: The pentahydrate dissolves in water for method-specific solution preparation.
Institutional suitability: The product can support school, college, university, research and quality-control laboratories when handled correctly.
Who Should Buy This Product?
This product is suitable for properly equipped school chemistry laboratories, college science departments, university chemistry laboratories, polytechnic institutes, teacher-training laboratories, research facilities, quality-control departments and institutional procurement teams that require analytical-grade Copper Sulphate.
It may also suit chemistry teachers, lecturers, trained laboratory technicians, analysts and researchers who need a verified reagent for crystallisation, solution preparation, qualitative analysis, electrochemistry or approved analytical procedures.
This product is not intended for household use, direct skin application, self-treatment, food use, animal feed, agricultural improvisation, drinking-water treatment, pond treatment or unsupervised student handling.
Usage and Handling Summary
Copper(II) Sulphate Pentahydrate should be handled only by trained personnel according to the product label, current Merck Safety Data Sheet, institutional chemical-hygiene plan and approved laboratory procedure.
Wear tightly fitting chemical splash goggles or suitable eye and face protection, protective gloves and a laboratory coat. Avoid generating or inhaling dust, and prevent the solid or solution from contacting the eyes, mouth, skin and clothing.
Do not eat, drink or smoke while handling this product. Wash hands and exposed skin thoroughly after use. Use clean, dry and compatible tools and do not return unused material to the original container.
For solution preparation, add the measured solid to the specified amount of suitable water and stir until dissolved. Use only the concentration required by the approved method. Clearly label all prepared solutions with their identity, concentration, date, hazards and responsible person.
For heating experiments, use small quantities, heat-resistant equipment and direct supervision. Avoid touching hot containers and do not overheat the material. Heating changes the hydration state and may release irritating or hazardous decomposition products at higher temperatures.
For spills, prevent dust formation and keep the material away from drains, soil and surface water. Trained personnel should collect the solid mechanically and place it in a labelled chemical-waste container. Copper-containing solutions and contaminated materials must be disposed of as regulated waste.
For eye contact, rinse immediately and carefully with water for several minutes and obtain urgent medical attention. If swallowed, follow the current SDS and seek medical or poison-centre advice. Do not give anything by mouth to an unconscious person.
Store at 2–30°C in the original tightly closed container in a dry, secure chemical-storage area. Protect it from contamination, moisture, unauthorised access and incompatible materials.
