3、Molecular Weight: 249.7
4、CAS: 7758-98-7
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. Above 150℃, it loses water and form Anhydrous Copper Sulfate which absorbs water easily. It’s freely soluble in water and aqueous solution is acidic. PH value of 0.1mol/L aqueous solution is 4.17（15℃）. It’s freely soluble in glycerol 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.

Toxicity:Oral-Rat LD50: 300 mg/kg
Odor:Pleasant odor
Experimental Properties:On heating dec above 560 degree|Hydroscopic, with conversion to the pentahydrate in moist air below 30 °C|Dielectric constant: 10.3 @ 17 to 22 °C
Air and Water Reactions:Soluble in water.
Reactive Group:Salts, Acidic
Reactivity Profile:Anhydrous CUPRIC SULFATE serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 (NTP, 1992). Both act as acidic salts, corrode metals and irritate tissues.
Autoignition Temperature:Not flammable (USCG, 1999)
