Zinc sulfate heptahydrate Chemical Properties,Uses,Production
Chemical Properties
Colorless crystals, small needles, or granular, crystalline powder; without odor; astringent, metallic taste. Efflorescent in air. Solutions acid to litmus. Loses 7H2O at 280C. Soluble in water and glycerol; insoluble in alcohol.
Uses
Zinc sulfate heptahydrate is widely used as a coagulant in the production of rayon. It finds an application in the manufacturing of calico printing, wood preservation and lithopone. It is the source of zinc which is supplied in animal feeds, fertilizers and agricultural sprays. It is utilized as electrolytes for zinc plating and surface treating agents. It is also used as a mordant in dyeing, preservative for skin and leather and in medicine as an astringent and emetic.
Definition
ChEBI: A hydrate that is the heptahydrate form of zinc sulfate.
General Description
Zinc sulfate heptahydrate has various industrial applications. It is widely employed as an electrolyte for zinc electroplating and for the storage of solar energy in various solar appliances. Its crystals exhibit diamagnetism.
Agricultural Uses
Zinc sulphate heptahydrate (ZnSO4?7H2O), also called
white vitriol, is the most common form of zinc sulphate.
It forms zinc sulphate monohydrate above 70°C and
anhydrous salt at 280°C, and is used as a mordant and a
styptic (to check bleeding).
Industrial uses
Zinc sulfate (ZnSO4·7H2O) is a white powder, very soluble in water (i.e. 37% at 20 °C). Zinc sulfate is primarily used in base-metal flotation as a depressant for sphalerite. Zinc sulfate has been used to depress talc in by-product molybdenum circuit.
Safety Profile
Human poison by an unspecified route. Poison experimentally by subcutaneous, intravenous, and intraperitoneal routes. Moderately toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and ZnO. See also ZINC SULFATE.
Purification Methods
Crystallise it from aqueous EtOH or dilute H2SO4 below 39o when it forms the heptahydrate, and between 39o and 70o it forms the hexahydrate, and above 70o the monohydrate is stable. The anhydrous salt is obtained from the hydrates by heating at 280o or lower temperatures in a current of dry air. It decomposes to ZnO and SO2 at 767o. The solubility of the heptahydrate in H2O is 5.88% at 0o, 61.92% at 30o, 66.61% at 35o and 70.05% at 39o.
