Copper sulfate is an inorganic compound, inorganic industry used to manufacture other copper salts such as cuprous 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, may also contain impurities and appear light gray-green, is a soluble copper salt. The relative density is 3.603, the solubility in water at 25 °C is 23.05g, insoluble in ethanol and ether, soluble in water, the aqueous solution is blue, it is a strong acid and weak alkali salt, the hydrolyzed solution is weakly acidic, and it has a strong ability to kill pathogens, and is widely used in the prevention and control of fish diseases in aquaculture. The solution is concentrated and crystallized, copper sulfate pentahydrate blue crystals can be obtained, commonly known as chole, stone gall, copper alum or blue alum, toxic, odorless, with metal astringency, very stable at room temperature and pressure, no deliquescence, in dry air will gradually weather, heating to 45 °C loss of Chemicalbook two-molecule crystal water, 110 °C loss of four-molecule crystal water, 150 °C loss of all crystal water to become anhydrous (water absorption can be converted into cholelite), 650 °C is decomposed into copper oxide and sulfur trioxide. Copper sulfate aqueous solutions appear blue due to the hydration of copper ions, and this property is commonly used in laboratories to test the presence of water. In real production and life, it is often used to refine fine copper, and mixed with hydrated lime can be used to make pesticide Bordeaux liquid. The copper ions in copper sulfate can destroy the three-dimensional structure of proteins, denaturing them. When determining protein concentration, alkali is often added to the protein, and then copper sulfate solution is added, at which point the solution turns purple, this reaction is called the diurea reaction. Copper sulfate is a heavy metal salt, toxic, adult lethal dose of 0.9g/kg. If ingested, immediately consume protein-rich foods such as milk and egg white, or use EDTA calcium and sodium salt to detoxify.

Copper sulfate can be used to kill fungi. Mixed with lime water to produce Bordeaux liquid, which is used to control fungi on crops such as lemons and grapes. Dilute solutions are used for sterilization and snail removal in aquariums. Since copper ions are toxic to fish, the amount must be strictly controlled. Most fungi require only very low concentrations of copper sulfate to be killed. In addition, copper sulfate can also be used to control E. coli. Ketone sulfate aqueous solution has a strong bactericidal effect, and is mainly used in agriculture to control fruit trees, malt, potatoes, rice and other diseases, with good effects, but poor effect on rust and powdery mildew. At the same time, Chemicalbook, which produces medicinal damage to plants, and is only used on crops with strong tolerance for copper ion drugs or fruit trees in the dormant period. It is a prophylactic fungicide that needs to be used before the onset of disease. It can also be used for algae removal in rice fields and ponds. It is also a trace element fertilizer, can improve the stability of chlorophyll, prevent chlorophyll from being destroyed prematurely, promote crop absorption, crop copper deficiency when losing green, fruit trees lack copper, fruit small fruit, pulp hard, serious fruit tree death, copper-sensitive crops are cereal crops such as wheat, barley, oats, etc., mainly used for seed treatment and extra-root top dressing.
