Magnesium iodide

The Magnesium iodide, with the CAS registry number 10377-58-9, is also known as Iodic acid magnesium salt . Its EINECS number is 222-432-0. It belongs to the product categories of Crystal Grade Inorganics; Inorganic Salts; Magnesium Salts; MagnesiumMetal and Ceramic Science; Salts; Synthetic Reagents. This chemical's molecular formula is MgI₂ and molecular weight is 269.34. What's more, its systematic name is magnesium diiodide. It should be sealed and stored in cool and dry places. Magnesium iodide is stable at high heat under a hydrogen atmosphere, but decomposes in air at normal temperatures, turning brown from the release of elemental iodine.

Preparation: this chemical can be prepared from magnesium oxide, magnesium hydroxide, and magnesium carbonate by treatment with hydroiodic acid:

MgO + 2 HI → MgI₂ + H₂O

Mg(OH)₂ + 2 HI → MgI₂ + 2 H₂O

MgCO₃ + 2 HI → MgI₂ + CO₂ + H₂O

When you are using this chemical, please be cautious about it as the following:
