Abstract

The stabilities of a number of carbonates, both minerals and synthetic compounds, were determined by dissolving them in water saturated with 1 atm. carbon dioxide at 25 degrees C. and 1 atm. total pressure. The pH of the solution was monitored continuously and the equilibrium value determined by extrapolating the pH-time data to infinite time. This equilibrium pH value was used to obtain the standard free energies of formation of the carbonates. The values obtained are listed below and are compared, where data are available, with values listed in U.S. Bureau of Standards Circular 500 or in Latimer9s Oxidation Potentials.

  • The Gibbs energies of formation (ΔGf°) of MnCO3 range from −809.89 kJ/mol to −818.81 kJ/mol with solubility products (log_Ksp) from −9.43 to −10.99.

    “The Gibbs energies of formation (ΔGf°) of MnCO3 range from − 809.89 kJ/mol to − 818.81 kJ/mol with solubility products (log_Ksp) from − 9.43 to − 10.99 [5, 14].”

  • Literature ΔGf° values for MnCO3(s) range from −809.89 ± 0.73 to −818.81 kJ/mol, including −812.53, −813.0, −814.6, −816.05 ± 1.38, −816.32 ± 0.07, −816.6 ± 0.2, and −816.7 kJ/mol.

    “The various ΔGf° values for MnCO3(s) found in the literature ranged from − 809.89 ± 0.73 kJ/mol [5] to − 818.81 kJ/mol [14], including − 812.53 kJ/mol [45], − 813.0 kJ/mol [39], − 814.6 kJ/mol [14], − 816.05 ± 1.38 kJ/mol [46], − 816.32 ± 0.07 kJ/mol [41], − 816.6 ± 0.2 kJ/mol [47] and − 816.7 kJ/mol [42].”

  • The solubilities of MnxCa1-xCO3 solid solutions in the present work were generally lower than data calculated using the empirical expression from experimental electrochemical cell data, related to the ΔGf° value for MnCO3 being too large.

    “The solubilities of the MnxCa1-xCO3 solid solutions in the present work were generally lower than the data calculated using the empirical expression derived from the experimental electrochemical cell data [5], which was related to the ΔGf° value of − 809.89 ± 0.73 kJ/mol for MnCO3 being too large in comparison to those (− 812.53 ~ − 818.81 kJ/mol) in the present work and other studies [14, 39, 41,”

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.
