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


Hardness ions are typically coined with sulfate, chloride, carbonate, or bicarbonate ions. For consistency, concentrations are generally converted to the equivalent concentration as calcium carbonate (CaCO 3 ) and expressed in terms of hardness as calcium carbonate.

Orientations of carbonate ions in human tooth enamel …

With the use of CO3-3 radical ions as probes, it is concluded that the carbonate ions substitute in the apatite lattice of human tooth enamel in two different ways. Most of the carbonate ions in the apatite lattice are aligned with their symmetry axis parallel to the c axis, whereas the remaining carbonate ions are aligned with their symmetry axis perpendicular to the c axis.
