Copper sulfate
Copper sulfate (cupric sulfate) is an inorganic compound with the formula CuSO4. It is white or off-white powder, and the aqueous solution is weakly acidic and bluish When crystallized from an aqueous solution, blue copper sulfate pentahydrate (CuSO4·5H2O, also known as cholerite) is formed, and this principle can be used to test the presence of water. It decomposes after heat loss of crystal water, is stable at room temperature and pressure, does not delix, and will gradually weather in dry air.
Copper sulfate is an important raw material for the preparation of other copper-containing compounds, which is not only a fertilizer, but also a widely used fungicide. Bordeaux liquid, copper soap liquid and copper ammonium preparation are prepared with copper sulfate and lime milk, soap and ammonium bicarbonate.

First, agriculture bactericide Copper sulfate can be used as an effective fungicide to prevent and control various crop diseases. For example, in grape farming, copper sulfate can be used to combat downy mildew; In the cultivation of fruit trees, it can play a certain role in the prevention and control of anthracnose and black star disease. Its bactericidal principle is mainly that copper ions can destroy the membrane structure of pathogenic bacteria, so that the substances in the cell are leaked out, thus inhibiting the growth and reproduction of pathogenic bacteria. Fertilizer additive Copper sulfate can be used as an additive to trace element fertilizer to provide copper for crops. Copper is one of the essential trace elements for plant growth, it participates in photosynthesis, respiration, protein synthesis and other physiological processes of plants. Appropriate amount of copper can improve the yield and quality of crops and enhance the resistance of plants to stress.
2. Industrial field Electroplating industry Copper sulfate is an important component of electroplating solution in electroplating industry. For example, for electroplating copper, a uniform and dense copper coating can be formed on the surface of metal products to improve the corrosion resistance, electrical conductivity and beauty of the metal. In the process of electroplating, under the action of electric field, copper ions are reduced to metal copper on the cathode, so as to achieve the purpose of electroplating. Printing and dyeing industry Copper sulfate is used as a mordant in printing and dyeing industry. Mordant can make the dye better combined with the fiber, improve the firmness of dyeing and color brightness. For example, in the dyeing of silk and wool, copper sulfate is often used in combination with acid dyes to make the dyeing effect more ideal. Chemical industry Copper sulfate is an important raw material for the preparation of other copper compounds. For example, copper hydroxide can be prepared by reacting copper sulfate with sodium hyroxide, and basic copper carbonate can be prepared by reacting with sodium carbonate. In addition, copper sulfate can also be used in the synthesis of catalysts, pigments, preservatives and other chemical products.
3. Medical field emetic In medicine, copper sulfate has been used as an emetic. When the human body ingests toxic substances, a small amount of copper sulfate solution can be taken orally to stimulate the gastric mucosa and cause vomiting, thereby discharging toxic substances. However, due to its high toxicity, it has been used less. Topical disinfectant Copper sulfate solution has certain antibacterial effect and can be used for local disinfection. For example, in the treatment of some skin infections, a wet compress with copper sulfate solution can be used. However, attention should be paid to concentration control to avoid skin irritation and damage.
4. Aquaculture algaecide Copper sulfate can be used to control algae growth in aquaculture ponds. Excess algae will consume oxygen in the water and affect the living environment of aquatic animals. Appropriate use of copper sulfate can effectively kill algae and keep water clean. Insect repellent It has a certain effect on the parasite of some aquaculture animals. For example, copper sulfate can be used to repel parasites such as wheel worms and oblique tube worms on the surface of fish bodies. The dosage should be strictly controlled when used to avoid poisoning aquatic animals.
V. Other areas Analytical chemistry In analytical chemistry, copper sulfate is often used in some chemical analysis methods. For example, as a reagent to detect proteins, copper sulfate will produce color changes after binding with proteins, and can be used for quantitative analysis of protein content. Wood preservation Copper sulfate solution can be used for wood preservative treatment. It can penetrate into the interior of the wood, inhibit the growth of wood decay bacteria, and extend the service life of the wood. Swimming pool disinfection A small amount of copper sulfate can be added to swimming pool water to inhibit algae growth and disinfect it. However, it is also necessary to strictly control the dosage to ensure the health and safety of swimmers.
