1、Chemical Name: Ferrous Sulfate
2、Molecular Formula : FeSO4·7H2O, FeSO4·nH2O
3、Molecular Weight: Heptahydrate :278.01
4、CAS: Heptahydrate: 7782-63-0; Dried: 7720-78-7
5、Character: Heptahydrate: It’s blue-green crystals or granules, odorless with astringency. In dry air, it’s efflorescent. In moist air, it oxidizes readily to form a brown-yellow, basic ferric sulfate. It’s soluble in water, insoluble in ethanol.
6、Usage: It is used as nutritional supplement(iron fortifier) and fruit and vegetable colorant.
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.
