Measurements were made using new third-kind electrochemical cells that do not require a complicated model for solute speciation or corrections for liquid-liquid junction potentials. The average value of ΔGf0[CaMg3(CO3)4(S)](−4195.6±6.4 kJ/mol) measured in these electrochemical cells agrees, within experimental error, with values determined calorimetricaUy (e.g., −4203.4 ± 1.6 kj/mol: Hemingway and Robie, 1973) and electrochemically (−4188.6 ± 1.0 kj/mol: Gamsjäger, 1989). Our results demonstrate the utility of this new electrochemical method in the study of metal carbonate equilibria of geochemical importance. This content is PDF only.

An investigation of Mg-carbonate systems found that the first species formed is metastable nesquehonite (25°C, 1 bar PCO2), followed by metastable hydromagnesite (120°C, 3 bar).

A low ratio of Mg2+ to CO3 2- could overcome the increased hydration activity of Mg2+ ions, allowing for easier adsorption on the crystal surface.
“A low ratio of Mg 2+ to CO 3 2-could overcome the increased hydration activity of Mg 2+ ions, as carbonate anions have a larger radius and are not completely surrounded by water.This allows for easier adsorption on the crystal surface.66”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
