Physical Characteristics

-Appearance: White, free-flowing powder or granular crystals, odorless

-Solubility: Readily soluble in water; slightly soluble in ethanol; insoluble in acetone

-Density: 3.28 g/cm³

-Hygroscopicity: Highly hygroscopic - absorbs moisture readily from air

-pH: 4.0-5.6 (20°C, 50g/L aqueous solution)

-Stability: Stable under normal conditions; decomposes at 238-280°C

Chemical Characteristics

-Forms stable monohydrate above 70°C

-In air, it can effloresce (lose water) to form anhydrous powder

-Aqueous solutions exhibit weak acidity

Primary Uses (Food-Grade)

1. Nutritional Supplement (Zinc Fortifier)

-Food Industry: Used as a zinc fortification agent in various food products to prevent zinc deficiency

-Dietary Applications: Added to processed foods, beverages, and dietary supplements as a source of essential zinc

-Regulatory Compliance: Food-grade purity requirement typically 99.0%-100.5%

2. Animal Nutrition

-Feed Additive: Widely used as a zinc supplement in animal feed formulations

-Livestock Health: Prevents zinc deficiency disorders in cattle, poultry, and swine

3. Food Processing Aid

-Processing Agent: Functions as a processing aid in food manufacturing (must be removed from final products unless residual levels are regulated)

-Water Treatment: Permitted in drinking water systems at concentrations up to 0.006 g/kg (2.4 mg/L as Zn)

4. Other Industrial Applications (Non-Food)

-While primarily used in food and nutrition, zinc sulfate monohydrate also has these applications:

-Agriculture: Foliar sprays and fertilizers to treat zinc deficiency in crops

-Chemical Manufacturing: Raw material for producing zinc compounds and zinc barium white pigment

-Electroplating: Electrolyte in zinc plating processes

-Textile Industry: Mordant in dyeing processes and material for rayon production

-Wood Preservation: Wood and leather preservative agent
