1.Chemical Name: ferrous sulfate
2.Molecular Formula : FeSO4·7H2O, FeSO4·nH2O
3.Molecular Weight: 278.02(Heptahytrate)
4.CAS: 7782-63-0(Heptahydrate), 7720-78-7(Monohydrate)
5.Character:Pale,blue-green crystals or granules that are efflorescent in
dry air.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 nutrient, fruit and vegetable chromogenic
reagent.
7.Packing: It is packed with plastic bag as inner layer, and a compound
plastic woven bag as the outer layer. The net weight of each bag is 25kg.
8.Storage and Transport: It should be stored in a dry and ventilating
warehouse, kept away form water and moisture during transport, unloaded with
care so as to avoid damage to bags. Furthermore, it should be stored separately
from poisonous substances.
