Uses:
1. used as analytical reagents, such as can be used in biology to configure the identification of reducing sugars Ferrin reagent and identification of proteins in the B solution of the bioconjugate reagent, but usually is now used;
2. used as food grade chelating agent and clarifying agent, used in leather eggs and wine production process;
3. industrial areas. Used in the manufacture of other copper salts such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, copper monoazo dyes such as reactive brilliant blue, reactive violet, etc.; coatings industry for the production of anti-fouling paints for the bottom of the ship; electroplating industry used as a main salt of the full bright acidic copper plating and copper ions additives; printing and dyeing industry used as a mordant and a fine dyed fabric as a co-oxidizer; organic industry used as a catalyst for the synthesis of intermediates in the spices and dyes, the It is used as a catalyst for the synthesis of spices and dye intermediates in organic industry and as a polymerization inhibitor for methyl methacrylate. The anhydrous salt is used to catalyze the transacetal reaction. Anhydrous salts react with potassium permanganate to form an oxidizing agent for the conversion of primary alcohols.
4. In agriculture, it is mixed with lime water to produce Bordeaux solution, which is used as a fungicide to control fungi on crops and prevent rotting of fruits, etc.; since copper ions are toxic to fish, the dosage must be strictly controlled. Breeding industry is also used as the main raw material of feed additives trace elements copper;
5. Used as dehydrating agent for alcohols and organic compounds. Gas desiccant.
6. chemistry education, copper sulfate is often included in children's chemistry lab reagents for crystal formation tests and copper plating experiments. Because of its toxicity, it is not recommended for use by young children. Copper sulfate can also be used to demonstrate the process of crystals losing water to weathering and gaining water of crystallization. In middle school lab exams, the law of conservation of mass is verified using the replacement reaction that occurs between copper sulfate and iron. Sulfuric acid can also be made.
7. It is used in the medical field as an emetic.
