Product Usage
Copper sulfate is an inorganic compound that is used in the inorganic industry to manufacture other copper salts such as cuprous chloride, copper chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, etc. The common form of copper sulfate is crystal, anhydrous copper sulfate is a white crystal powder, which may also be light gray green due to impurities, and is a soluble copper salt. The relative density is 3.603, the solubility in water is 23.05g at 25ºC, insoluble in ethanol and ether, easily soluble in water, the aqueous solution is blue, is a strong acid and weak base salt, the hydrolytic solution is weakly acidic, has a strong ability to kill pathogens, and is widely used in aquaculture to prevent and control fish disease. The solution is concentrated and crystallized to obtain blue crystal of copper sulfate pentahydrate, commonly known as cholerite, stone gall, copper alum or blue alum, toxic, odorless, with metal astringency, stable at room temperature and pressure in Chemicalbook, no deliquination, will gradually weather in dry air, lose two molecular crystal water when heated to 45ºC, and lose four molecular crystal water when 110ºC. At 150 ° C, all crystal water is lost to form anhydrous matter (water absorption can be transformed into chalcoalum), and at 650 ° C, it is decomposed into copper oxide and sulfur trioxide. An aqueous solution of copper sulfate has a blue color due to the hydrated copper ion, which is commonly used in the laboratory to test the presence of water. In real life, it is often used to refine copper and mixed with hydrated lime to produce pesticide Bordeaux liquid. Copper ions in copper sulfate can destroy the three-dimensional structure of proteins and denature them. To determine the protein concentration, a base is often added to the protein, followed by a solution of copper sulfate, at which time the solution will turn purple, and this reaction is called the biuret reaction.
