Zinc sulfate heptahydrate, also known as zinc alum, is an inorganic compound with the molecular formula ZnSO4 · 7H2O. It is a colorless orthorhombic crystal prismatic crystal that appears as a white crystalline powder. This compound is soluble in water and slightly soluble in ethanol.
When heated, zinc sulfate decomposes at 200°C and fully decomposes at 770°C. It is commonly used in various industries such as media colorants, wood preservatives, and in the production of zinc salts. Additionally, zinc sulfate is utilized in medicine, man-made fibers, electrolysis, electroplating, pesticides, and as a bleach in the paper industry.
However, caution must be taken as zinc sulfate is harmful if swallowed, can cause serious eye damage, and has high toxicity to aquatic organisms. It is crucial to prevent its release into the environment to avoid long-term adverse effects on water ecosystems.
Shanghai Titop Chemicals Co., Ltd. offers high-quality zinc sulfate heptahydrate that can be used as a supplementary fertilizer in agriculture to provide the essential trace element zinc for plant growth.
