essential information

Copper sulfate, an inorganic compound with the chemical formula CuSO4. It is a white or off white powder. The aqueous solution is weakly acidic and appears blue. But when crystallized from an aqueous solution, blue copper sulfate pentahydrate (CuSO4 · 5H2O, also known as bilite) is generated, which can be used to test the presence of water. After losing its crystalline water due to heat, it decomposes and is very stable at room temperature and pressure, without deliquescence. It will gradually weather in dry air.
Copper sulfate is an important raw material for the preparation of other copper containing compounds. Mixing with lime milk can produce Bordeaux mixture, which can be used as a fungicide. Also used as an electrolyte for electrolytic refining of copper.

application area 

Used as analytical reagents, such as solution B for configuring Ficin reagent for identifying reducing sugars and biuret reagent for identifying proteins in biology, but usually prepared and used on the spot; It is used as a food grade chelating agent and clarifying agent in the production process of Century egg and wine;

Industrial sector. Used for manufacturing other copper salts such as cuprous chloride, cuprous chloride, copper pyrophosphate, cuprous oxide, copper acetate, copper carbonate, copper monoazo dyes such as Reactive Brilliant Blue, Reactive Purple, etc; The paint industry is used to produce anti fouling paint for ship bottoms; Used as the main salt and copper ion additive for fully bright acidic copper plating in the electroplating industry; Used as a mordant and oxygen aid for precision dyed fabrics in the printing and dyeing industry; Organic industry is used as a catalyst for synthesizing fragrances and dye intermediates, and as a polymerization inhibitor for methyl methacrylate. Anhydrous salts are used for catalyzing the conversion of aldehydes. Anhydrous salt reacts with potassium permanganate to produce an oxidant used for the conversion of primary alcohols.

In the agricultural field, Bordeaux mixture is mixed with lime water to produce Bordeaux mixture, which is used as a fungicide to control fungi on crops and prevent fruit decay; Due to the toxicity of copper ions to fish, the dosage must be strictly controlled. The aquaculture industry is also used as the main raw material for trace element copper as a feed additive; Dehydrating agent for alcohols and organic compounds. Gas desiccant.

In chemistry education, copper sulfate is usually included in children's chemical laboratory reagents for crystal formation experiments and copper electroplating experiments. Due to its toxicity, it is not recommended for young children to use. Copper sulfate can also be used to demonstrate the process of crystal dehydration weathering and obtaining crystal water. In the junior high school experimental exam, the substitution reaction between copper sulfate and iron was used to verify the law of conservation of mass. It can also produce sulfuric acid.

Used as an emetic in the medical field.

Packaging, Storage, Transportation, and Safety
Transportation precautions:

When shipping, the packaging should be intact and the loading should be secure. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with acids, alkalis, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures. The vehicle should be thoroughly cleaned after transportation.

Storage method:

Store in a cool, dry, and well ventilated warehouse. Stay away from sources of fire and heat. Keep the container sealed. It should be stored separately from acidic, alkaline, and edible chemicals, and avoid mixing storage. The storage area should be equipped with suitable materials to contain leaked materials.
