CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Zinc chloride is a white crystalline solid. It is soluble in water. It is corrosive to metals and therefore irritating to the skin, eyes and mucous membranes. It is used for preserving wood, in soldering fluxes, as a catalyst in chemical metals and manufacturing, and for many other uses. |
|---|---|
| Color/Form | White, very deliquesce granules, or fused pieces or rods |
| Odor | Odorless |
| Boiling Point | 1350 °F at 760 mmHg (NIOSH, 2023) |
| Melting Point | 554 °F (NIOSH, 2023) |
| Solubility | 435 % at 70 °F (NIOSH, 2023) |
| Density | 2.91 at 77 °F (NIOSH, 2023) - Denser than water; will sink |
| Vapor Pressure | 0 mmHg (approx) (NIOSH, 2023) |
| Stability/Shelf Life | In weak aqueous solution has tendency to form insoluable basic salt by hydrolysis; about 1/2 its weight of ammonium chloride has been used for stabilization |
| Autoignition Temperature | Not flammable (USCG, 1999) |
| Decomposition | When heated to decomposition it emits toxic fumes of /hydrogen chloride and zinc oxide/. |
| Corrosivity | Fume corrosive to metals /zinc chloride fumes/ |
| pH | Aqueous solutions of zinc chloride are acidic (pH = 1.0 for 6 M) |
| Refractive Index | INDEX OF REFRACTION: 1.681; 1.713 |
| Other Experimental Properties | With much water, some zinc oxylchloride is formed |
| Chemical Classes | Metals -> Metals, Inorganic Compounds |
