ZnCl2 is the compound zinc chloride, which is highly water soluble and can conduct electricity when dissolved in water. It is formed through chlorination when chlorine bonds to zinc metal. Electrolysis may be used to decompose the compound into chlorine gas and zinc.
In commercial applications, zinc chloride is used in welding due to its capability of dissolving oxides on metal surfaces. It is also a component in dry cell batteries, as it prevents battery leakage due to its ability to absorb water. In medicine, zinc chloride is used in antiseptics as well as disinfectants. It is also a component in deodorants.
