Copper Sulphate Anhydrous – 500 gram Packs

Copper Sulphate Anhydrous, also known as anhydrous Copper(II) Sulphate or cupric sulphate, is an inorganic salt with the chemical formula CuSO₄. It consists of copper(II) ions and sulphate ions and differs from copper sulphate pentahydrate because it contains no water of crystallization. The anhydrous compound is a white to off-white crystalline solid or powder that readily absorbs moisture from the surrounding environment. It dissolves in water to form solutions containing copper(II) and sulphate ions, making it relevant to inorganic chemistry experiments, solution preparation, and studies of hydration and dehydration. Copper Sulphate Anhydrous is used in educational laboratories, analytical investigations, and selected research procedures where the anhydrous form is specifically required. This 500 gram pack provides a practical quantity for laboratory applications, subject to the stated reagent grade, experimental requirements, and appropriate safety procedures.

Frequently Asked Questions About Copper Sulphate Anhydrous

What is Copper Sulphate Anhydrous used for in laboratories?

Copper Sulphate Anhydrous is used in hydration experiments, preparation of aqueous copper(II) sulphate solutions, inorganic chemistry practicals, and selected analytical procedures. It is especially relevant when a method requires copper sulphate without water of crystallization. The appropriate grade and purity depend on the requirements of the particular experiment or analytical method.

What is the chemical formula of Copper Sulphate Anhydrous?

The molecular and empirical formula of Copper Sulphate Anhydrous is CuSO₄. Each formula unit contains one copper atom, one sulphur atom, and four oxygen atoms. Its formula mass is approximately 159.61 g/mol, which is lower than that of copper sulphate pentahydrate because the pentahydrate contains five additional water molecules per formula unit.

What is the CAS number of Copper Sulphate Anhydrous?

The CAS Registry Number for anhydrous Copper(II) Sulphate is 7758-98-7. Copper sulphate pentahydrate has the different CAS number 7758-99-8. Confirming the chemical form is important when ordering reagents and calculating the quantities required for laboratory solutions or chemical reactions.

Why is Copper Sulphate Anhydrous white instead of blue?

Anhydrous Copper Sulphate is generally white to off-white because it lacks the water of crystallization present in blue copper sulphate pentahydrate. When the anhydrous material absorbs moisture, hydration can change its appearance toward blue. This property makes it useful for supervised demonstrations of hydration and the relationship between composition and physical appearance.

How should Copper Sulphate Anhydrous be stored and handled safely?

Store it in a tightly closed, moisture-resistant container in a cool, dry, well-ventilated area. Avoid inhaling dust and prevent contact with the eyes and skin. Wear suitable gloves and safety goggles, consult the applicable Safety Data Sheet, and prevent the chemical from entering drains or the environment. Follow institutional procedures for spills and chemical-waste disposal.

Storage Conditions for Copper Sulphate Anhydrous

Store Copper Sulphate Anhydrous in a tightly sealed, moisture-resistant container in a cool, dry, well-ventilated location. Minimize exposure to humid air because the material can absorb moisture and become hydrated. Keep the container clearly labelled and segregate the chemical from incompatible substances according to the applicable Safety Data Sheet. Follow supplier-specific storage instructions and institutional chemical-storage procedures.

Precautions for Handling Copper Sulphate Anhydrous

Review the current Safety Data Sheet before use and wear suitable protective gloves, safety goggles, and laboratory clothing. Avoid generating or inhaling dust and prevent contact with the eyes and skin. Use appropriate ventilation when weighing or transferring the powder. Prevent spills from reaching drains or the environment, and collect residues for approved chemical-waste disposal. Follow institutional spill-response procedures and ensure appropriate supervision during educational laboratory activities.
