Copper Sulphate Anhydrous- 1 Kg 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 is distinguished from copper sulphate pentahydrate by the absence of water of crystallization. The anhydrous compound is a white to off-white crystalline solid or powder and is hygroscopic, meaning it can absorb moisture from its surroundings. It dissolves readily in water and forms blue copper(II) sulphate solutions. These properties make it useful for studying hydration and dehydration, ionic reactions, solution preparation, and inorganic chemistry. Copper Sulphate Anhydrous is relevant to educational practicals, analytical investigations, and selected research procedures where its specific chemical form is required. This 1 kg pack is intended for laboratory applications consistent with the stated reagent grade and applicable safety requirements.

Key Features of Copper Sulphate Anhydrous

• Anhydrous chemical composition: Contains copper(II) sulphate without water of crystallization, with the formula CuSO₄.
• Characteristic physical appearance: Occurs as a white to off-white crystalline solid or powder in its anhydrous state.
• Hygroscopic behaviour: Absorbs moisture from the environment and can become hydrated, making moisture control important during storage and handling.
• Water solubility: Dissolves in water to produce solutions containing copper(II) and sulphate ions, supporting various inorganic chemistry experiments.
• Hydration chemistry: Useful for investigating the changes in appearance and chemical composition associated with hydration and dehydration of copper sulphate.

Laboratory Applications of Copper Sulphate Anhydrous

• Hydration and dehydration experiments: Used in supervised chemistry practicals to demonstrate the effects of water uptake and the conversion between anhydrous and hydrated copper sulphate.
• Solution preparation: Used to prepare aqueous copper(II) sulphate solutions for suitable laboratory experiments, with calculations accounting for the anhydrous formula mass.
• Inorganic chemistry practicals: Supports experiments involving ionic compounds, copper(II) ions, sulphate ions, and selected precipitation or displacement reactions.
• Analytical chemistry: Can serve as a copper-containing reagent or starting material in appropriate analytical procedures, subject to method-specific purity and grade requirements.
• Research and chemical synthesis: Used as a starting material in selected preparations of copper-containing compounds and investigations of inorganic reaction behaviour.

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 particularly relevant when an experiment requires copper sulphate without water of crystallization. The required grade and purity depend on the specific experimental 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 molecular or formula mass is approximately 159.61 g/mol, which differs from copper sulphate pentahydrate because the pentahydrate contains five water molecules.

What is the CAS number and molecular weight of Copper Sulphate Anhydrous?

The CAS Registry Number for anhydrous Copper(II) Sulphate is 7758-98-7. Its formula mass is approximately 159.61 g/mol. Copper sulphate pentahydrate has a different CAS number, 7758-99-8, and a formula mass of approximately 249.68 g/mol, so the two forms should not be treated as interchangeable in calculations.

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 associated with the familiar blue pentahydrate. When it absorbs sufficient moisture, hydration can change its appearance toward blue. This property makes it useful for supervised experiments demonstrating hydration and changes in the physical characteristics of inorganic salts.

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 place. Avoid generating or inhaling dust and prevent contact with the eyes and skin. Wear suitable gloves and eye protection, consult the applicable Safety Data Sheet, and keep the chemical away from incompatible materials. Prevent release into drains and the environment.

Storage Conditions for Copper Sulphate Anhydrous

Store Copper Sulphate Anhydrous in a tightly sealed, moisture-resistant container in a cool, dry, well-ventilated area. Because the material is hygroscopic, minimize exposure to humid air and close the container promptly after use. Keep it away from incompatible materials, including finely powdered reactive metals and strong bases, and follow the applicable Safety Data Sheet and institutional 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 inhaling dust and prevent contact with the eyes and skin. Use appropriate ventilation when weighing or transferring the powder. Do not mix it with incompatible substances, and prevent spills from reaching drains or the environment. Collect waste for approved chemical disposal and follow institutional spill-response procedures.
