Treating the solution of different soluble magnesium salts with alkaline water induces the precipitation of the solid hydroxide Mg(OH) 2: Mg 2+ + 2 OH − → Mg(OH) 2. As Mg 2+ is the second most abundant cation present in seawater after Na +, it can be economically extracted directly from seawater by alkalinisation as described here above. On ...
Magnesium gluconate – Mg(HOCH 2 (CHOH) 4 CO 2) 2; Magnesium hydride – MgH 2; Dimagnesium phosphate – MgHPO 4; Magnesium hydroxide – Mg(OH) 2; Magnesium hypochlorite – Mg(OCl) 2; Magnesium iodide – MgI 2; Magnesium molybdate – MgMoO 4; Magnesium nitrate – Mg(NO 3) 2; Magnesium oxalate – MgC 2 O 4; Magnesium peroxide – MgO 2 ...
6 Mg(OH) 2 + 6 Cl 2 → 5 MgCl 2 + Mg(ClO 3) 2 + 6 H 2 O. Magnesium perchlorate is a white powder that is easily soluble in water, which can be obtained by the reaction of magnesium oxide and perchloric acid. The hexahydrate crystallizes from the solution, and then it is dried with phosphorus pentoxide in a vacuum at 200~250 °C to obtain the ...
A basic salt of an alkali metal or alkaline earth metal [2] (this includes Mg(OH) 2 (magnesium hydroxide) but excludes NH 3 ). Any base that is soluble in water and forms hydroxide ions [3] [4] or the solution of a base in water. [5] (This includes both Mg(OH) 2 and NH 3, which forms NH 4 OH.) The second subset of bases is also called an ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Brucite is the mineral form of magnesium hydroxide, with the chemical formula Mg() 2.It is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists; and formed during serpentinization of dunites.

Some basic forms such as artinite (Mg 2 CO 3 (OH) 2 ·3H 2 O), hydromagnesite (Mg 5 (CO 3) 4 (OH) 2 ·4H 2 O), and dypingite (Mg 5 (CO 3) 4 (OH) 2 ·5H 2 O) also occur as minerals. All of those minerals are colourless or white. Magnesite consists of colourless or white trigonal crystals. The anhydrous salt is practically insoluble in water ...
