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.
