Zinc sulfate heptahydrate, as an important inorganic zinc salt, plays a significant role in various fields due to its extensive applications and favorable chemical properties.Colorless monoclinic prismatic crystals or white granules/powder.
Purity
• Industrial-grade zinc sulfate heptahydrate typically has a purity of up to 99%.
• High-purity products can reach a purity of over 99.5%.
Safety and Storage
• Safety Information: Irritating to the eyes and toxic to aquatic organisms. Ingestion should be avoided, and contact with the eyes should be prevented.
• Storage Conditions: Store in a sealed container, avoiding direct sunlight and moisture.
Chemical Properties
• Zinc sulfate heptahydrate gradually effloresces in dry air, losing its water of crystallization.
• It loses all water of crystallization when heated to 280°C and decomposes above 500°C.
• Its aqueous solution is weakly acidic.
