Zinc acetate dihydrate is a colorless to white crystalline inorganic compound commonly used in pharmaceuticals, chemical synthesis, and as a dietary zinc supplement.
🏭⚗️ Production
It is typically produced by reacting zinc oxide or zinc carbonate with acetic acid, followed by crystallization to obtain the dihydrate form.
🔬 Properties
The chemical formula is Zn(CH₃COO)₂·2H₂O with a molar mass of approximately 219.5 g/mol. It appears as white, odorless crystals, is soluble in water and alcohol, and forms mildly acidic solutions. It is stable under normal conditions but may lose water on heating.
🧪 Applications
Zinc acetate dihydrate is used as a zinc supplement in medicine, especially for treating zinc deficiency and reducing symptoms of the common cold. It is also used as a reagent in laboratories, a catalyst in chemical reactions, and a mordant in dyeing.
⚠️ Safety
Generally considered safe in controlled doses, but may cause irritation to the skin, eyes, or respiratory tract upon contact or inhalation of dust. High doses can cause gastrointestinal discomfort. Use protective gloves and store in a dry, cool place away from acids and bases.
