Magnesium carbonate is ordinarily obtained by mining the mineral magnesite. Seventy percent of the world's supply is mined and prepared in China. [9] Magnesium carbonate can be prepared in laboratory by reaction between any soluble magnesium salt and sodium bicarbonate: MgCl 2 (aq) + 2 NaHCO 3 (aq) → MgCO 3 (s) + 2 NaCl(aq) + H 2 O(l) + CO 2 (g)
It is the most common cave carbonate after calcite and aragonite. [2] The mineral thermally decomposes, [5] [6] over a temperature range of approximately 220 °C to 550 °C, releasing water and carbon dioxide leaving a magnesium oxide residue. Hydromagnesite was first described in 1836 for an occurrence in Hoboken, New Jersey. [3]
Magnesium compounds are compounds formed by the element magnesium (Mg). These compounds are important to industry and biology, including magnesium carbonate , magnesium chloride , magnesium citrate , magnesium hydroxide (milk of magnesia), magnesium oxide , magnesium sulfate , and magnesium sulfate heptahydrate ( Epsom salts ).
It represents the pentahydrate of magnesium carbonate, and has the total formula MgCO 3 ·5H 2 O . [2] Landsfordite was discovered in 1888 in a coal mine in Lansford, Pennsylvania. It crystallizes in the monoclinic system (space group P2 1 /c [3]) and typically occurs as colorless to white prismatic crystals and stalactitic masses. [4]
Artinite is a hydrated basic magnesium carbonate mineral with formula: Mg 2 (CO 3)(OH) 2 ·3H 2 O. It forms white silky monoclinic prismatic crystals that are often in radial arrays or encrustations. It has a Mohs hardness of 2.5 and a specific gravity of 2.
Magnesium bromide – MgBr 2; Magnesium carbonate – MgCO 3; Magnesium chloride – MgCl 2; Magnesium citrate – C 6 H 6 MgO 7; Magnesium oxide – MgO; Magnesium perchlorate – Mg(ClO 4) 2; Magnesium phosphate – Mg 3 (PO 4) 2; Magnesium sulfate – MgSO 4; Magnesium bicarbonate – Mg(HCO 3) 2; Magnesium boride – MgB 6; Magnesium ...
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.
