1、Chemical Name: Copper Sulfate
2、Molecular Formula: CuSO4·5H2O
3、Molecular Weight: 249.7
5、Character: It’s dark blue triclinic crystal or blue crystalline powder or granule. It smells like nasty metal. It effloresces slowly in dry air. Relative density is 2.284. When above 150℃, it loses water and form Anhydrous Copper Sulfate which absorbs water easily. It’s soluble in water freely and aqueous solution is acidic. PH value of 0.1mol/L aqueous solution is 4.17（15℃）. It’s soluble in glycerol freely and dilute ethanol but insoluble in pure ethanol.
6、Usage: It is used as nutritional supplement, antimicrobial agent, firming agent and processing aid.
7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
