Anhydrous salt reaction with potassium permanganate to generate a kind of antioxidant, is used for primary alcohol conversion.
Agriculture, is mixed with limewater generated after bordeaux mixture, as a fungicide, is used to control the crops on the fungus, to prevent rotting fruit, etc;
Because of the copper ion toxic to fish, dosage must be strictly controlled.
Breeding is also used as the main raw material of feed additive trace element copper;
Used for alcohol dehydrating agent and organic compounds.
Chemical education, copper sulfate is often included in the children's chemical experiment reagent, used in the production of crystal test and the copper plating.
Because of its toxicity, not recommended for children to use.
Copper sulfate can also be used to demonstrate the crystal water loss of weathering and water of crystallization process.
In the junior middle school experiment exam, is validated with the displacement reaction of copper sulfate and iron law of conservation of mass.
Can also be producing sulfuric acid.
Used as emetic medical field.
