6. Character: Blue crystalline granules or powder. At 30℃, it loses 2 molecules of crystalline water; at 110℃, it loses 4 molecules of crystalline water; and at 250℃, it becomes a white powder-like anhydrous substance. It is readily soluble in water, and the aqueous solution is acidic. The pH of a 0.2mol·L-1 aqueous solution is 4.0. Non-flammable, toxic and irritating. It decomposes under high heat to produce toxic sulfide fumes.
7. Usage: It is used as catalysts, nutritional supplements, pesticides and analytical reagents, etc
8. Packing: It is packed with polythene bag as the inner layer, and plastic woven bag as the outer layer. 500KG net each jumbo bag; 25KG net each small bag.
9. Storage and Transport: It should be stored in a dry, clean, and ventilated warehouse, kept away from water and moisture during transport, unload with care so as to avoid damaging the bags. Be cautious to keep away from moisture and hot.
