Magnesium Iodide Formula

Magnesium Iodide Formula

The Extramarks website and mobile application discuss the Magnesium Iodide Formula, also known as the diiodo magnesium formula. The several hydrates in this chemical compound are typical ionic halides and do not dissolve in water. Magnesium Iodide has the molecular or chemical formula MgI2 (anhydrous).

The Magnesium Iodide Formula is a crystalline, odourless substance that is white in colour. Using magnesium oxide, magnesium carbonate, and magnesium hydroxide and treating them with hydroiodic acid allows for Magnesium Iodide Formula synthesis. The Magnesium Iodide Formula is frequently used to create chemicals for organic synthesis.

Under a hydrogen environment and in the presence of a lot of heat, the Magnesium Iodide Formula is stable. The Magnesium Iodide Formula decomposes at room temperature and turns brown as a result of the emission of elemental iodine.

Students are recommended to register themselves on the Extramarks website in order to learn more about the Magnesium Iodide formula from the knowledgeable instructors at Extramarks. Additionally, notes on the Magnesium Iodide Formula are available for download on the Extramarks website and mobile application.

Magnesium Iodide Formula Structure

The Magnesium Iodide Formula is denoted as  MgI2. The Magnesium Iodide Formula also appears in a variety of forms, including MgI2 (anhydrous), MgI26H2O (hexahydrate), and MgI28H2O. (octahydrate).

Anhydrous Magnesium Iodide has a molar mass of 278.1139 g/mol, hexahydrate Magnesium Iodide weighs 386.2005 g/mol, and octahydrate Magnesium Iodide weighs 422.236 g/mol. Iodine anion I2+ and magnesium cation Mg2+ interact structurally.

The Magnesium Iodide Formula exists an anhydrous form with a hexagonal crystal structure, a hexahydrate form with a monoclinic structure, and an octahydrate form with an orthorhombic structure.

Properties Of Magnesium Iodide Formula

The Magnesium Iodide Formula has a white crystalline solid appearance and no odour. As an anhydrous solid, it has a density of 4.43 g/cm3, a hexahydrate solid’s density is 2.353 g/cm3, and an octahydrate solid’s density is 2.098 g/cm3.

The Magnesium Iodide Formula is also soluble in alcohol, ether, and ammonia. It is very soluble in water. The Magnesium Iodide Formula can hold 74 J/mol K of heat. Even though it is stable, it reacts to air and moisture. It decomposes at temperatures exceeding its melting point of 637oC.

Occurrence of Magnesium Iodide

The Magnesium Iodide Formula is a typical inorganic salt found in sea salt in nature. It is typically instantly accessible in the majority of volumes, nanopowder, submicron, and high purity. The Magnesium Iodide Formula is prepared in laboratories by scientists.

Preparation of Magnesium Iodide

By treating Magnesium Carbonate and Magnesium Oxide with Hydroiodic Acid, students can create Magnesium Iodide Formula. The Extramarks website and mobile application have the answers to questions concerning the Magnesium Iodide Formula.

Reactions of Magnesium Iodide

The Magnesium Iodide Formula is stable at high heat under the hydrogen environment. However, the Magnesium Iodide Formula turns brown as elemental iodine is released and decomposes in the air at normal or room temperature. Additionally, it entirely separates and forms Magnesium Oxide when heated in air.

Uses of Magnesium Iodide

The Magnesium Iodide Formula is typically applied in internal medicine. Magnesium Iodide Formula can be used to prepare chemicals for organic synthesis, albeit it still has few industrial applications.

Health and Safety Hazards of Magnesium Iodide

If the Magnesium Iodide Formula gets in contact with the skin and irritates the eyes, it poses minimal risk. It also irritates when swallowed or breathed. The chemical contains iodine, which makes it harmful to the thyroid. Furthermore, prolonged and repeated exposure to the Magnesium Iodide Formula might seriously harm organs.

Some people may get vomiting and breathing issues after consuming the Magnesium Iodide Formula. Long-term eye exposure can lead to blindness. Despite not being flammable, it can produce Magnesium Hydroxide when exposed to moisture.

Solved Example for You

Below is a solved example for students’ reference to give them an idea of how the questions pertaining to the Magnesium Iodide Formula might appear in the final examinations:

  1. Describe a process for making Magnesium Iodide.

Solution: By reacting Magnesium Hydroxide and Hydroiodic Acid, students can make Magnesium Iodide meaning Magnesium Iodide and water is produced when Magnesium Hydroxide and Hydroiodic Acid combine.
