Zinc chloride is an inorganic compound that is a chloride of zinc. The following are some properties of zinc chloride:

1. Appearance: Zinc chloride is colorless or white crystalline solid, the common form is anhydrous zinc chloride (ZnCl2) or hexahydrate zinc chloride (ZnCl2·6H2O).

2. Solubility: zinc chloride is easily soluble in water, and the solubility increases with the increase of temperature. In water, zinc chloride breaks down into zinc ions (Zn2+) and chloride ions (Cl-).

3. High corrosion: Zinc chloride is highly corrosive and can react with many metals, including iron, aluminum and so on.

4. Electrical conductivity: Zinc chloride is an electrolyte and can conduct electricity. In solution, zinc chloride can form ions that can conduct an electric current.

5. Chemical reaction: Zinc chloride can react with some compounds, such as reacting with iodide to produce iodine ions and zinc chloride complexes.

6. Application: Zinc chloride is widely used in chemical experiments and industry, often as a catalyst, dehydrating agent, solvent and flux in metallurgical industry.
