Zinc Chloride General Information
Zinc cloride is the name of chemical compound with the formula ZnCl2 and its hydrates. Zinc chloride, of which nine crystalline forms are known, is colorless or white and highly soluble in water. ZnCl2 itself is hygroscopic and even deliquescent. Samples should therefore be protected from sources of moisture, including the water vapor present in ambient air. Zinc chloride finds wide application in textile processing, metallurgical fluxes, and chemical synthesis. No mineral with this chemical composition as ZnCl2 is known although a very rare mineral, simonkolleite, Zn5(OH)8Cl2·H2O is known.
Structure and basic properties
Four crystalline forms, so-called polymorphs, of ZnCl2 are known, and in each case the Zn2+ ions are tetra-hedrally coordinated to four chloride ligands. Rapid cooling of molten ZnCl2 gives a glass, that is, a rigid amorphous solid. Additionally ZnCl2 forms hydrates and at least one mixed hydroxide, ZnClOH.
The covalent character is of the anhydrous material is indicated by its relatively low melting point of 275C. Further evidence for covalency is provided by the high solubility of the dichloride in etherial solvents such as wherein it forms adducts with the formula ZnCl2L2 where L = ligand such as O(C2H5)2. Consistent with the Lewis acidity of Zn2+, aqueous solutions of ZnCl2 are acidic solutions: a 6 M aqueous solution has a pH of 1.
Four hydrates of zinc chloride are known. ZnCl2(H2O)4 crystallizes from aqueous solutions of zinc chloride. Also characterized are ZnCl2(H2O)n where n = 1, 1.5, 2.5, and 3. When hydrated zinc chloride is heated, one obtains a residue of ZnOHCl.In aqueous solution, zinc chloride fully dissociates into Zn2+. Thus, although many zinc salts have different formulas and different crystal structures, these salts behave very similarly in aqueous solution. For example, solutions prepared from any of the polymorphs of ZnCl2 as well as other halides (bromide, iodide) and the sulfate can often be used interchangeably for the preparation of other zinc compounds. Illustrative is the preparation of zinc carbonate:
ZnCl2(aq) + Na2CO3(aq) → ZnCO3(s) + 2 NaCl(aq)
Zinc Chloride is used for Friedel Craft Reaction, Azotropic or Azeotropic Distillation, Desiccation & Karl Fischer.
