Magnesium Iodide Formula, we also know it by the name diiodomagnesium formula. It is an inorganic salt which we can easily find in seawater. In addition, it is a chemical that has numerous hydrates that are usually ionic halides that are highly soluble in water.
The chemical and molecular formula of magnesium iodide is
The molar mass of each form is: anhydrous magnesium iodide is 278.1139 g/mol, hexahydrates magnesium iodide is 386.2005 g/mol, and 422.236 g/mol for ocathydrate form of magnesium iodide. Structurally, the magnesium cation
It exists in an anhydrous form that has a hexagonal crystal structure, a monoclinic structure for a hexahydrate form and an orthorhombic structure for octahydarte form.
In nature, it occurs in sea salt and is a common inorganic salt. Generally, it is immediately available in most volumes, nanopowder, submicron, and high purity. Scientists prepare them in laboratories.
We can prepare magnesium iodide from magnesium oxide and magnesium carbonate by treatment with hydroiodic acid. The reactions are:
At high heat under the hydrogen atmosphere it is stable. However, it decomposes in the air at normal temperature or room temperature by turning brown from the release of elemental iodine. Moreover, when we heat it in air, it completely decomposes off and from magnesium oxide.
An alternative method to prepare
It appears as a white crystalline solid that does not have any odor. The density of its different form are: as an anhydrous solid its density is
Moreover, it is soluble in ether, ammonia, and alcohol. In water, it is highly soluble. Its heat capacity is 74 J/mol K. Although it is stable but under moisture and air it reacts. Its melting point is
Generally, we use it in internal medicine. Also, it has few commercial uses, still, we can use it to prepare compounds for organic synthesis.
It is slightly hazardous if comes in contact with the skin and causes irritation in the eyes. Also, causes irritation if ingested or inhaled. However, the substance is toxic to the thyroid as it has iodine in it. Moreover, repeated and prolonged exposure to it can cause serious damage to organs.
Its ingestion can cause vomiting and breathing problems in some peoples. Long exposure to the eyes can cause blindness. Although it is nonflammable but can react with moisture to form magnesium hydroxide.
Question: Mention a method to prepare magnesium iodide?
Solution: We can prepare magnesium iodide by the reactions of magnesium hydroxide with hydroiodic acid:
Explanation: When magnesium hydroxide reacts with hydroiodic acid it forms magnesium iodide and water.
