The effects of secular calcium and magnesium concentration ...

The concentrations of dissolved magnesium [Mg 2+] and calcium [Ca 2+] are of particular importance for the carbon cycle because these ions greatly reduce the activity of carbonate ion [CO 32−] via strong anion‐cation interaction [e.g., Garrels and Thompson, 1962; Millero and Schreiber, 1982] and because [Ca 2+] is a direct factor in the saturation state of CaCO 3 [e.g., Harvie et al., 1984 ].

Calcium carbonate - Wikipedia

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at ...

Why can’t sodium and calcium be extracted by using carbon ...

Sodium and calcium (and even magnesium) will reduce any oxides of carbon into the elemental form. It's because of their powers as reducing agents which are a lot higher than that of carbon. Carbon can at best reduce oxides of metals which cannot displace hydrogen from acids, no matter how strong the acid.
