Variation in production, input and preservation of metastable calcium carbonate off Somalia …

To improve our understanding of the Late Pleistocene and Holocene carbonate system of the western Arabian Sea a high-resolution sedimentary record off Somalia has been analysed. The 15.26-m-long piston core 905 comprises a complete record of the last 90,000 years. We have measured concentrations of carbonate minerals, i.e., aragonite, calcite, Mg-calcite, and …

Why can''t calcium bicarbonate (not calcium carbonate) exist as a solid…

Answer (1 of 4): Well it can’t be made from aqueous solution at any rate. In a solution of CO2 there would be an equilibrium between dissolved carbon dioxide, H+, carbonate (CO3—) and bicarbonate (HCO3-) ions, where the balance lies depends on levels of those

Equilibria with Calcium Carbonate

Calcium Carbonate and Water Minerals containing calcium carbonate have different solubilities in water. Two types of carbonate minerals are listed in the table above. An average value for the K sp of calcium carbonate is about 5 x 10-9. K sp = [Ca 2+][CO 3 2-] = 5 x 10-9

Calcium Carbonate Solubility

7/1/2016· Calcium Carbonate Solubility. The solubility of calcite (CaCO 3, Calcite) seems to show an inverse solubility with respect to temperature. This seems contradictory to what is normally observed in the field. The confusion occurs because of the assumed presence of carbon dioxide (CO 2 ). Normally atmospheric air contains approximately 300 ppm CO 2.

What is Calcium Carbonate? (with pictures)

This dissolved calcium carbonate forms calcium bicarbonate, which then precipitates out of solution to become an insoluble solid (it is only soluble in a carbonic acid, not pure water). This precipitation is what forms the stalactites and stalagmites that form within caves (and the lime scale around your bathtub that is so hard to scrub off).
