Magnesium Chloride, Formula, Preparation Method, Chemical Properties

Magnesium Chloride

Magnesium chloride is the chemical compound and contains the typical iconic halides that can be highly soluble in water. It can be obtained from the brine or sea water. It is the most abundant mineral and highly content the ancient seabeds. These magnesium metal contributes the 25.5% elemental. The anhydrous is the most priority metal to produce the magnesium metal. The systematic IUPAC name is known as magnesium chloride. The chemical or molecular formula of magnesium chloride is MgCl2. It is also known as the magnesium dichloride.

Structural Formula

This is the structural formula of the magnesium chloride:

Magnesium Chloride

Chemical Formula

The chemical formula of the magnesium chloride is MgCl2.

Preparation Method

By using the dow process the magnesium chloride is produced by treating the solution of magnesium hydroxide and hydrochloric acid.

Mg(OH)2 + 2HCl → MgCl2 + 2H2O

It crystallizes the cadmium chloride at the high temperatures upto 300oC. by heating the chloride salt it can produced the anhydrous with the hexamine complex to coordinate with the six water ligands. It is required to the absence of the metal by the direct electrolysis with the magnesium metal.
