Characteristic：

Chemical formula CuSO4, white powder, relative density is 3.603, solubility in water is 23.05g at 25℃, insoluble in ethanol and ether, easily soluble in water, water solution is blue, is a strong acid and weak base salt, because the hydrolysis solution is weakly acidic. When the copper sulfate solution is concentrated and crystallized, the blue crystal of copper sulfate pentahydrate can be obtained, commonly known as gallerum, copper alum or blue alum, with a relative density of 2.284. Bile alum is very stable at room temperature and pressure, no deliquescence, and will gradually weathered in dry air. When heated to 45℃, it loses two molecules of water of crystal, 110℃ when it loses four molecules of water of crystal, 150℃ when it loses all water of crystal and becomes anhydrous. Anhydrous material is also easy to convert into water absorption of biliary alum. This property is often used to test whether certain liquid organic substances contain trace amounts of water. When it is heated to 650℃, it can be decomposed into black copper oxide, sulfur dioxide and oxygen.

Copper sulfate is one of the most important copper salts. It is widely used in electroplating, printing and dyeing, pigment, pesticide and so on. The inorganic pesticide Bordeaux solution is a mixture of copper sulfate and lime milk. It is a good fungicide and can be used to prevent and control a variety of crop diseases. In bordeaux, France in 1878, the vine disease occurred most of the dead, and the trees on both sides of the road, afraid of pedestrians to pick to eat on the trunk with quick lime and copper sulfate solution, the trunk gray, dare not eat pick pedestrians looked uncomfortable, the tree did not die, knows the mixture with sterilization ability, the further study called bordeaux mixture. Preparation of Bordeaux solution, copper sulfate and lime (preferably a block of fresh lime) ratio is generally 1∶1 or 1∶2, the amount of water is also determined by different crops, without disease and seasonal temperature factors. It is better to use the "two liquid method" when preparing, that is, the first copper sulfate and quicklime are mixed with the required half amount of water, and then pour into another container at the same time, constantly stirring, then get the sky blue gelatinous liquid. Bordeaux liquid to be prepared and used now, because it is placed for a long time, the gelatinous particles will gradually become large and sink and reduce the efficacy. Copper sulfate is also commonly used in the preparation of other copper compounds and as an electrolyte in the electrolysis of refined copper. Copper sulfate pentahydrate can be made from copper or copper oxide and sulfuric acid after the reaction, concentrated crystallization. In the laboratory, anhydrous copper sulfate can be prepared by oxidizing copper metal with concentrated sulfuric acid.

Application：

• 1, copper sulfate used in the manufacture of other copper salts, such as cuprous chloride, copper chloride, pyrophosphate copper, cuprous oxide, copper acetate, copper carbonate, etc. Dyes and pigments industry used in the manufacture of copper single accidentally ammonia dyes such as reactive brilliant blue and reactive violet.
• 2, analysis reagent, several kinds of chemical analysis is needed to the copper sulfate. It is used in Fiji reagent and Lin bancroft reagent in inspection of reducing sugar. In the reaction, reduction of copper (ii) a precipitation insoluble red cuprous oxide. Copper sulfate can also be used in double shrink gland reagents used to detect protein.
• 3, copper sulfate can be used for inspection of anemia. The blood drip into the copper sulfate solution, if the blood contains enough hemoglobin, blood will quickly sink;If the hemoglobin content is insufficient, blood samples will be suspended in solution. Flame reaction of copper sulfate, turquoise, color blue is much more than barium ion.
• 4, copper sulfate can be used in organic synthesis in organic synthesis. Anhydrous salt used in catalytic turn acetal. Anhydrous salt reaction with potassium permanganate to generate a kind of antioxidant, is used for primary alcohol conversion. Organic industrial catalyst used for synthetic spices and dyes intermediates, methyl methacrylate polymerization inhibitor.
