Nature and Chemical Properties of Zinc Compounds
Nature And Chemical Properties Of Zinc Compounds
A chemical compound is usually formed by the combination of two or more chemical elements in a fixed ratio. Zinc is a chemical element in the periodic table with a specific molecular formula (Zn) and own molecular weight. Chemical elements are combined to form new chemical compounds which are used for various purposes. The ratio of the presence of each element in a chemical compound is expressed by the chemical formula.
The Zinc Iodide is formed by the combination of two chemical elements zinc (Zn) and iodine (I). This is an anhydrous chemical compound which absorbs water from the atmosphere very quickly. This appears as a white solid in nature with a density of 4.74 g/cm cube. The chemical formula of the compound is ZnI2. Molecular mass of the zinc iodide compound is 319.22 g/mol. Melting point of this compound is 446 degrees Celsius. This compound is shows solubility in water of 450 g/ 100ml at the temperature of 20 degree Celsius.
It can be prepared in two ways; one is by direct reaction of zinc and iodine in refluxing ether and the other one is by the presence of aqueous solution with zinc and iodine. Boiling point of zinc iodide is 1,150 degree Celsius at which the compound is again decomposes into zinc and iodine by decomposition.
Structure And Applications Of Zinc Iodide
Zinc iodide has an unusual crystalline structure with a tetragonal shape. Zinc iodide molecule is linear with Zn-I bond length of 238 pm. It has the CAS number of 10139-47-6. CAS Registry number or CASRN is assigned by chemical abstract service (CAS) to every chemical substance for its easy identification and information.
It is used as an X-ray opaque penetrant to improve the contrast in industrial radiography. It is used as a stain in electron microscopy to view the microstructure in conjunction with osmium tetroxide. This was widely used in neurocytological studies for fixation and staining method. It is also used in tissue sample examination including of bone marrow cells, epidermal Langerhans cells, and lymphoid tissue for examinations over microscope. Zinc iodide and other zinc halogen forms are rechargeable in aqueous solution in both positive and negative electrode compartments.
