The carbonate saturometer was used to determine the effect of Mg 2+ ion on the solubility of four different calcareous materials. It was found that a high area calcite ≈ 13.5m 2 /g had a higher solubility than a low area calcite ≈ .8m 2 /g and that the difference in surface areas of these calcites modified the effect of Mg 2+ ion on their solubilities. Data indicated that the mineralogy of the solid carbonates can modify the effect of Mg 2+ ion on the solubility of the solid phase. Carbonates which contained appreciable Mg showed a decrease in solubility with increasing Mg 2+ ion, whereas carbonates with low or no Mg showed an increase in solubility.
