Zinc Chloride

A white crystalline compound. The anhydrous salt, which is deliquescent, can be made by the action of hydrogen chloride gas on hot zinc. It has a relatively low melting point and sublimes easily, indicating that it is a molecular compound rather than ionic. Various hydrates also exist. Zinc chloride is used as a catalyst, dehydrating agent, and flux for hard solder.
