Magnesium chloride is an ionic compound, which can be electrolysed in a molten state to form magnesium and chlorine gas. The properties of magnesium bromide and magnesium iodide are similar. [citation needed] HMgX (X=Cl,Br,I) can be obtained by reacting the corresponding magnesium halide with magnesium hydride. [3]
Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
Magnesium hydroxychloride [1] is the traditional term for several chemical compounds of magnesium, chlorine, oxygen, and hydrogen whose general formula xMgO·yMgCl 2 ·zH 2 O, for various values of x, y, and z; or, equivalently, Mg x+y (OH) 2x Cl 2y (H 2 O) z−x.
chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII) oxide radical; dichlorine monoxide, Cl 2 O ...
These salts are colorless or white solids that are highly soluble in water. These compounds and their solutions, both of which occur in nature, have a variety of practical uses. Anhydrous magnesium chloride is the principal precursor to magnesium metal, which is produced on a large scale. Hydrated magnesium chloride is the form most readily ...
If further heated to 120 °C it decomposes to water, oxygen, chlorine, and magnesium oxide. [2] As confirmed by X-ray crystallography, the di- and hexahydrates feature octahedral Mg 2+ centers. The other ligands are water, exclusively in the hexahydrate. In the dihydrate, chlorate is also coordinated and functions as a bridging ligand. [1]
The two principal factors in determining the form of the lattice are the relative charges of the ions and their relative sizes. Some structures are adopted by a number of compounds; for example, the structure of the rock salt sodium chloride is also adopted by many alkali halides, and binary oxides such as magnesium oxide.
3 anion, whose chlorine atom is in the +5 oxidation state. The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid. Other oxyanions of chlorine can be named "chlorate" followed by a Roman numeral in parentheses denoting the oxidation state of chlorine: e.g., the ClO −
