Zinc chloride (ZnCl2) is an inorganic ionic compound and a white crystalline solid that is highly soluble in water and hygroscopic (attracts moisture). Known for its versatility, it is commonly used in soldering fluxes to clean metal surfaces, in wood preservation, textile processing, and chemical synthesis as a Lewis acid catalyst. The compound is highly soluble in water and organic solvents, and is often prepared by reacting zinc with hydrochloric acid.
Physical PropertiesWhite, odorless, highly soluble crystalline powder that can be deliquescent, requiring protection from air.Chemical Properties Acts as a Lewis acid, capable of forming four hydrates (e.g., ) and acting as a strong dehydrating agent.Industrial Uses Acts as a key ingredient in soldering flux to remove metal oxides, in textiles as a mordant, and for preserving wood against decay.
