Product Description
Basic Information

Product Name: Copper Sulfate Pentahydrate
Chemical Formula: CuSO4.5H2O
Molecular Weight: 249.68
Appearance: Blue crystal, presenting as irregular lumps or granules.
Melting Point: 110 °C (losing 4 crystal water molecules), 258 °C (losing all crystal water molecules).
Density: 2.284 g/cm³.
Solubility: Highly soluble in water, creating a vibrant blue aqueous solution. Slightly soluble in ethanol and glycerol.

Chemical Properties

Stability: Stable under normal temperatures and pressures. When heated to targeted temperatures, it gradually loses its crystal water.
Oxidizing Property: Possesses oxidizing qualities and acts as an oxidant in specific chemical reactions.
Reaction with Bases: Reacts with strong alkaline solutions to produce copper hydroxide precipitate. (e.g., CuSO4 + 2NaOH = Cu(OH)2↓ + Na2SO4)
Reaction with Metals: Undergoes active displacement reactions. For instance, reacting with iron deposits red copper on the iron's surface while forming ferrous sulfate. (e.g., Fe + CuSO4 = FeSO4 + Cu)

Product Uses

Agricultural Field: Serves as an essential fungicide and fertilizer. Prevents crop diseases like wheat rust and apple anthracnose. Feeds essential copper trace elements to plants to boost development, showing a significant yield increase in copper-responsive crops like rice and corn.
Industrial Field: Extensively utilized in electroplating, printing/dyeing, pigments, and battery manufacturing. Works as a key copper plating component for uniform, polished surfaces. Functions as a mordant in textile dyeing. Serves as a vital source material for creating blue and green pigments.
Medical Field: Used as an emetic, astringent, and disinfectant. Dosage needs strict control due to toxicity.
Laboratory Use: A standard laboratory reagent used for copper ion solutions, protein analysis, and identifying aldehyde groups. Also functions as a catalyst or reactant.
