Zinc sulphate

MF： O4SZn

MW： 161.45

CAS： 7733-02-0

Zinc sulphate is a colorless or white orthorhombic crystal or powder at room temperature. It has astringent properties and is easily soluble in water. The aqueous solution is acidic and slightly soluble in ethanol and glycerin. Pure zinc sulfate does not turn yellow when stored in the air for a long time, and loses water in dry air to become a white powder. There are many kinds of hydrates: zinc sulfate heptahydrate is stable hydrate in the range of 0-39℃, zinc sulfate hexahydrate at 39-60℃, and zinc sulfate monohydrate at 60-100Chemicalbook℃. When heated to 280°C, various hydrates completely lose crystal water, decompose into zinc oxysulfate at 680°C, further decompose above 750°C, and finally decompose into zinc oxide and sulfur trioxide at about 930°C. ZnSO4·7H2O and MSO4·7H2O (M=Mg, Fe, Mn, Co, Ni) form mixed crystals within a certain range.

Uses:

1. Industry

2. Medicine

3. Agriculture

Zinc sulfate is mainly used as a raw material for the preparation of pigment lithopone, lithopone and other zinc compounds. It is also used as a nutrient when animals are zinc-deficient, animal husbandry feed additives, and zinc fertilizer for crops (trace element Chemicalbook fertilizer) , An important material for man-made fibers, the electrolyte used in the electrolytic production of metallic zinc, mordants in the textile industry, medical emetics, astringents, fungicides, wood and leather preservatives, etc.
