Zinc chloride (formerly known as butter of zinc) is a white crystalline compound with the formula ZnCl2. The anhydroussalt, 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, a wood preservative for discouraging fungoid growths and as a flux for hard solder. Research Zinc Chloride
