Is carbon dioxide absorbed by calcium carbonate?

Actually CaCO3 does not react with CO2 under dry conditions but if water is present, the solid calcium carbonate reacts and dissolves in the water to give bicarbonate ions according to the overall reaction, CaCO3 + CO2 + H2O ---> Ca+2 +2HCO3- read more

When carbon dioxide (CO 2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. read more

Carbon dioxide reacts with quicklime (calcium oxide) to form limestone (calcium carbonate), in a process called carbonate looping. Other minerals include serpentinite, a magnesium silicate hydroxide, and olivine. read more
