    The solubility of calcium bicarbonate is relatively high, about 1 M, to perform practically feasible bioclogging and biocementation. However, production of calcium bicarbonate by dissolution of calcium carbonate during the treatment with CO 2 gives only low-concentration solution, about 10 mM, due to increase of pH that inhibits dissolution of

    Solubility of Calcium Carbonate The solubility of salts of weak acids is very pH dependent. The most important example of the pH dependence of solubility is for CaCO 3, which is the major component of sea shells, limestone, and marble. The pH dependence of the solubility can be explained because when

    Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO2 partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): CaCO3 ⇌ Ca + CO 3 Ksp = 3.7×10 to 8.7×10 at 25 °C where the solubility product for [Ca ][CO 3] is given as anywhere from Ksp = 3.7×10 to Ksp = 8.7×10 at 25 °C, depending upon the data source.

    Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO2 partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): CaCO3 ⇌ Ca + CO 3 Ksp = 3.7×10 to 8.7×10 at 25 °C where the solubility product for [Ca ][CO 3] is given as anywhere from Ksp = 3.7×10 to Ksp = 8.7×10 at 25 °C, depending upon the data source. What the equation means is that the product of molar concentration of calcium ions (moles of dissolved Ca per liter of solution) with the molar concentration of dissolved CO 3 cannot exceed the value of Ksp. This seemingly simple solubility equation, however, must be taken along with the more complicated equilibrium of carbon dioxide with water (see carbonic acid). Some of the CO 3 combines with H in the solution according to HCO 3 ⇌ H + CO 3 Ka2 = 5.61×10 at 25 °C HCO 3 is known as the bicarbonate ion. Calcium bicarbonate is many times more soluble in water than calcium carbonate—indeed it exists only in solution. Some of the HCO 3 combines with H in solution according to H2CO3 ⇌ H + HCO 3 Ka1 = 2.5×10 at 25 °C Some of the H2CO3 breaks up into water and dissolved carbon dioxide according to H2O + CO2(aq) ⇌ H2CO3 Kh = 1.70×10 at 25 °C And dissolved carbon dioxide is in equilibrium with atmospheric carbon dioxide according to where kH = 29.76 atm/(mol/L) at 25 °C (Henry constant), PCO2 being the CO2 partial pressure. For ambient air, PCO2 is around 3.5×10 atmospheres (or equivalently 35 Pa). The last equation above f
