Molecular Formula: CuSO4·5H2OMolecular Weight: 249.68 Properties:
blue transparent crystal, relative density: 2.29. Easily soluble in water, little air-slaking in the air ,aqueous solution is acidic;Soluble in methanol and glycerol; slightly soluble in ethanol.Transform into trihydrate salts(30°C),monohydrate salts(110 °C) when be heated;then 258°C change into white powders anhydrous salts.Use:
For the manufacture of other cupric salts(Copper cyanide,cupprous chloride,cupprous oxide); monoazo dyes contain copper; as poisoning agent for ship bottom antifouling paint ;as catalyst for the synthesis of perfumes and dyes intermediates; as bactericide, insecticides etc.
