Copper sulfate (CuSO4), is an inorganic compound widely used in industrial production and scientific research. The compound commonly exists as copper sulfate pentahydrate (CuSO4-5H2O) as blue crystals, commonly known as blue alum. The substance loses its water of crystallization under dry conditions and changes to anhydrous copper sulfate in the form of a white or off-white powder. Copper sulfate is usually prepared by the reaction of concentrated sulfuric acid and copper, or it can be obtained by treating a mixture of copper-bearing ores with sulfuric acid.
Industrially, copper sulfate is an important chemical raw material widely used in pesticides, plant and animal growth regulators, feed additives, and as a medium in the electroplating and dyeing industries. It also plays a role in water treatment for sterilization, algae control, and corrosion protection. Copper sulfate is both a fertilizer and a commonly used fungicide. Bordeaux solution, copper soap solution, and ammonium copper preparations, are made by preparing copper sulfate with lime milk, soap, and ammonium bicarbonate.
Copper sulfate is azure or slightly yellow granular crystals, aqueous solution is acidic, is a protective inorganic fungicide, relatively safe for humans and animals. Chemical formula CuSO4, generally for the pentahydrate CuSO4-5H2O, commonly known as bile alum; blue rhombohedral crystals; density 2.284 g/cm3. Copper sulfate is an important raw material for the preparation of other copper compounds. Mixed with milk of lime can be obtained "Bordeaux" solution, used as insecticide. Copper sulfate is also the electrolytic solution for electrolytic refining of copper.
