What is a Zinc chloride (ZnCl₂)?

Zinc chloride (ZnCl₂) is a salt of zinc, typically appearing as a colorless or white crystalline solid. It is highly soluble in water and has significant hygroscopic properties, meaning it readily absorbs moisture from the air. Zinc chloride is widely used in various chemical and industrial applications, especially as a flux in metalworking, as well as in adhesives and coagulating agents. It serves as a catalyst in oxidation and cross-coupling reactions. In industry, it is used for metal surface cleaning and wood preservation. It is also involved in the manufacturing of batteries, particularly as an electrolyte in dry cells. In medicine, zinc chloride has been used as a hemostatic agent but must be handled carefully due to its corrosive nature. Direct contact with skin or eyes can cause severe irritation, and ingestion or inhalation is harmful. Proper safety precautions are essential.
