Copper Sulfate Crystals

Copper sulfate  Chemical formula CuSO4. Generally pentahydrate CuSO4 · 5H2O, commonly known as cholesta; blue rhombic crystals; density 2.284 g cm 3. Copper sulfate pentahydrate can lose water gradually at different temperatures, lose 4 molecules of water at 110 ℃, lose 5 molecules of water at 150 ℃. Anhydrous copper sulfate is white powder; density of 3.603 g cm3; 25 ° C in water solubility of 23.05 g 100 grams of water, insoluble in ethanol and ether; water absorption is strong, blue after water absorption. Copper sulfate decomposed into CuO when heated to 650 ° C.

Analytical reagents, for example, can be used in the biology to determine the determination of reducing sugar and the identification of protein leucine reagent B solution, but usually with the current use;2. Can be used for food-grade chelating agents and clarifiers for preserved eggs and production process;3. Can be used as raw materials for the manufacture of other feed such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, copper single azo dyes such as active brilliant blue,4. Used as a fungicide for the production of antifouling paints in the coatings industry and in agriculture. The electroplating industry is used as an all-bright acid copper main salt.
