3. Properties
Physical Properties
- Appearance: Blue, odorless crystals.
- At 650°C, copper(II) sulfate decomposes into copper(II) oxide (CuO) and sulfur trioxide (SO3).
- The blue color is due to hydration water. When heated, the crystals lose water and turn grayish-white.
Chemical Properties
- Reaction with hydrochloric acid: Produces a green solution due to the formation of tetrachlorocuprate(II).
4. Applications
Water and Environmental Treatment
- Used for controlling algae and treating parasitic infections in aquatic animals.
- Utilized in water and wastewater treatment industries.
Textile and Dyeing Industry
- Widely used in textile printing and dyeing, producing blue and green colors in fabrics.
Agriculture and Plant Protection
- Ingredient in pesticides, antibiotics, and disinfectants.
- Used in animal feed and fertilizers, and as a catalyst in various processes.
Other Industries
- Applications in leather tanning, electroplating, battery manufacturing, and electro-engraving.
- Used in metal refining and ship painting industries.
5. Preparation
- Prepared by dissolving copper(II) oxide or copper carbonate in sulfuric acid solution.
- Can also be produced by slowly leaching low-grade copper ore in the presence of air, using certain bacteria to accelerate the process.
