Product Description
1.Chemical Name: Zinc Sulfate
2.Molecular Formula : ZnSO4·H2O, ZnSO4·7H2O
3.Molecular Weight: Monohydrate: 179.48; Heptahydrate: 287.54
4.CAS: Monohydrate:7446-19-7; Heptahydrate:7446-20-0
5.Character: It is colorless transparent prism or spicule or granular crystalline powder, odorless. Relative density is 1.957. Melting point is 100ºC. It's easily soluble in water and aqueous solution is acidic to litmus. It's slightly soluble in ethanol and glycerin. The monohydrate loses water at temperatures above 238ºC; heptahydrate effloresces in dry air at room temperature.
6.Usage: It is used as nutritional supplement(zinc fortifier) and processing aid. It's used in milk product, infant food, liquid and milk drinks, grain and its' products, table salt, soft drinks, maternal formula and coco powder and other flavor nutritional solid drinks.
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.
