Basic Information
Product Name: Copper(II) sulfate
CAS Number: 7758-98-7
Alias: Anhydrous copper sulfate, Cupric sulfate
Molecular Formula: CuSO4
Molecular Weight: 159.61 g/mol
IUPAC Name: Copper(II) sulfate
Structural Information
- Structure Type: Inorganic metal salt, sulfate compound
- Structural Features: Composed of copper(II) cations and sulfate anions. It is a typical ionic crystal and easily combines with water molecules to form various hydrates.
Physical & Chemical Properties
- Appearance: White or off-white crystalline powder
- Odor: Odorless
- Melting Point: 560 °C (decomposition)
- Density: 3.606 g/cm3 (20 °C)
- Solubility: Soluble in water and methanol; slightly soluble in ethanol; insoluble in acetone and ether
- Stability: Stable under dry normal temperature. Absorbs moisture readily in humid air to turn blue. Decomposes at high temperature to release sulfur oxide fumes. Reacts with strong bases, ammonia and reducing agents.
Synthesis & Applications
Synthesis Method
Produced by the reaction of copper metal or copper oxide with dilute sulfuric acid. After evaporation, crystallization and dehydration treatment, anhydrous copper sulfate is obtained.
Main Applications
- Chemical Reagent: Common analytical reagent for moisture detection and chemical analysis.
- Agriculture: Used as fungicide, pesticide and trace element fertilizer for crops.
- Electroplating Industry: Main raw material for copper plating solution.
- Water Treatment: Applied as algaecide and flocculant in water circulation systems.
- Industrial Raw Material: Used for manufacturing copper salts, pigments and dyestuffs.
Safety & Storage Instructions
- Hazard Classification: Harmful substance; irritates skin, eyes and respiratory tract. Toxic if swallowed.
- Personal Protection: Wear dust mask, safety goggles and chemical resistant gloves. Avoid dust inhalation and oral intake.
- Storage Condition: Keep containers tightly sealed. Store in cool, dry and well-ventilated area. Strictly prevent moisture absorption, and keep away from food, acids and reducing substances.
- Transportation: Classified as general hazardous chemicals. Prevent package damage, dampness and mixing with food goods during transit.
Quality & Spectral Data
- Purity: ≥99.0%
- Loss on Drying: ≤1.0%
- Water Insoluble Matter: ≤0.2%
- Iron (Fe): ≤0.01%
- IR Spectrum: Characteristic absorption peaks conform to standard reference spectrum
