A soluble zinc salt that serves equally as an agricultural micronutrient and as an electrolyte and reagent in metal and textile processing. It is used as a zinc micronutrient in fertilizers and animal feeds, as an electrolyte in zinc electroplating, as a mordant in textile dyeing and printing, as a flotation reagent in ore processing, and as a wood and hide preservative.
▸Agriculture: Zinc micronutrient for fertilizers and foliar sprays
▸Animal nutrition: Zinc supplement in feed premixes
▸Electroplating: Electrolyte in zinc-plating baths
▸Textiles: Mordant in dyeing and printing
▸Mineral processing: Flotation reagent and depressant
Physical Properties
Physical Description
Anhydrous zinc sulfate is a colorless crystalline solid. Zinc sulfate is also obtained as a hexahydrate, ZnSO4.6H2O, and as a heptahydrate ZnSO4.7H2O. All forms are soluble in water. All are noncombustible. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in the production of rayon, as a feed supplement, and as a fertilizer ingredient

Frequently Asked Questions
What is zinc sulfate used for?
Zinc sulfate (CAS 7733-02-0) is a water-soluble zinc salt used as a zinc micronutrient in fertilizers and animal feed, an electrolyte in zinc electroplating, a mordant in textile dyeing and printing, a flotation reagent in ore processing, and a wood and hide preservative.
What is the chemical formula for zinc sulfate?
Anhydrous zinc sulfate is ZnSO4 (CAS 7733-02-0). It is also commonly supplied as the monohydrate (ZnSO4·H2O) and heptahydrate (ZnSO4·7H2O), which differ in water of crystallization and zinc content per gram.
Is zinc sulfate water soluble?
Yes. Zinc sulfate is highly water soluble, which supports its use in liquid fertilizers, foliar sprays, plating baths, and flotation circuits where an aqueous zinc source is needed.
How does zinc sulfate ship under DOT?
Zinc sulfate is associated with UN 3077 for transport classification; the SDS specifies handling and packaging. RawSource provides the SDS and bulk quotes; confirm shipping requirements for your destination.
How is bulk zinc sulfate supplied and what does it cost?
RawSource supplies zinc sulfate as a bulk powder or crystal in industrial pack sizes with CoA available. Pricing depends on hydrate form, grade, and volume, so request a current bulk quote rather than a list price.
