Copper Sulfate
EVS
Product Description
copper sulfate is an inorganic compound that is used by the inorganic industry to make other copper salts such as cuprous chloride, cupric chloride, cupric pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc.
The common form of copper sulfate is Crystal, anhydrous copper sulfate is white crystal powder, and may also be light gray green due to impurities, which is a soluble copper salt. The relative density is 3.603, the solubility in water is 23.05g at 25 ° C, insoluble in ethanol and ether, soluble in water, the aqueous solution is blue, is a strong acid and weak alkali salt, the hydrolysis solution is weakly acidic, it has a strong ability to kill pathogens and is widely used in the prevention and treatment of fish diseases in aquaculture. The solution is concentrated and crystallized to obtain blue crystals of copper sulfate pentahydrate, commonly known as bile alum, Stone Gall, copper alum or Blue alum, toxic, odorless, with metal astringency, stable at normal temperature and pressure, not deliquescent, in dry air will gradually weathering, heated to 45 deg C when the loss of two molecules of crystal water, 110 deg C when the loss of four molecules of crystal water, it loses all the crystal water at 150 ℃ and becomes anhydrous (water absorption can be converted into bile alum), and decomposes into copper oxide and sulfur trioxide at 650 ℃.
The aqueous copper sulfate solution exhibits a blue color due to the hydrated copper ion, This property is commonly used in the laboratory to test for the presence of water. In the real production life, commonly used in the refining of refined copper, mixed with slaked lime can be prepared pesticide Bordeaux mixture. Copper ions in copper sulfate can destroy the three-dimensional structure of protein, so that denaturation. Determination of protein concentration is often added to the protein base, then add copper sulfate solution, the solution will turn purple, this reaction is called the Biuret reaction.
copper sulfate is a heavy metal salt, toxic, adult Lethal dose 0.9g/kg. If eating, should immediately eat a lot of milk, egg white and other protein-rich foods, or the use of EDTA calcium sodium detoxification.
Usage:
In the chemical industry for the manufacture of other copper salts such as cuprous cyanide, cuprous chloride, cuprous oxide and other products. The dye industry is used to produce copper-containing monoazo dyes such as reactive brilliant blue, reactive Violet, Phthalocyanine Blue and other copper complexing agents. It is also a catalyst for intermediates in organic synthesis, fragrances and dyes. The pharmaceutical industry is often used directly or indirectly as astringents and auxiliary raw materials for the production of isoniazid and pyrimethamine. The coating industry is used for copper oleate as a toxic agent for Ship Bottom antifouling paint. Electroplating industry for sulfate copper plating and wide temperature bright acid copper ion additive. Food grade is used as an antimicrobial agent, a nutritional supplement. Agricultural use as pesticides and copper-containing pesticides.
