  2. Magnesium carbonate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_carbonate

    Magnesium carbonate, Mg CO 3 (archaic name magnesia alba), is an inorganic salt that is a colourless or white solid. Several hydrated and basic forms of magnesium carbonate also exist as minerals .

  3. Artinite - Wikipedia

    en.wikipedia.org/wiki/Artinite

    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. It occurs in low-temperature hydrothermal veins and in serpentinized ultramafic rocks.

  4. Magnesite - Wikipedia

    en.wikipedia.org/wiki/Magnesite

    Magnesite can also be formed via the carbonation of magnesium serpentine (lizardite) via the following reaction: 2 Mg 3 Si 2 O 5 (OH) 4 + 3 CO 2 → Mg 3 Si 4 O 10 (OH) 2 + 3 MgCO 3 + 3 H 2 O. However, when performing this reaction in the laboratory, the trihydrated form of magnesium carbonate (nesquehonite) will form at room temperature. [6]

  5. Magnesium compounds - Wikipedia

    en.wikipedia.org/wiki/Magnesium_compounds

    Magnesium hypochlorite and magnesium chlorite are unstable compounds, they are easy to hydrolyze, the former generates basic salt Mg(OCl) 2 ·2Mg(OH) 2 and the latter generates hydroxide Mg(OH) 2; magnesium chlorate can be obtained by reacting magnesium carbonate with chloric acid and crystallizing hexahydrate from solution, which can also be ...

    en.wikipedia.org/wiki/Water_softening

    Resins are also available to remove the carbonate, bicarbonate, and sulfate ions that are absorbed and hydroxide ions that are released from the resin. [ 8 ] When all the available Na + ions have been replaced with calcium or magnesium ions, the resin must be recharged by eluting the Ca 2+ and Mg 2+ ions using a solution of sodium chloride or ...

  7. Lansfordite - Wikipedia

    en.wikipedia.org/wiki/Lansfordite

    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 ]

  8. Magnesium citrate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_citrate

    The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated).

  9. Hydromagnesite - Wikipedia

    en.wikipedia.org/wiki/Hydromagnesite

    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]
