Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

The serum calcium increased, not significantly, in the calcium carbonate group (group 1) [from 9.2 to 9.8 mg/dl (p = 0.05)], however it was not modified in the calcium acetate group (group 2). The serum phosphorus decreased significantly (p < 0.05) in both groups, independently of the calcium levels.

Water Research Center - Alkalinity and Stream Water …
If CaCO3 actually accounts for most of the alkalinity, hardness in CaCO3 is equal to alkalinity. Since hard water contains metal carbonates (mostly CaCO3) it is high in alkalinity. Conversely, unless carbonate is associated with sodium or potassium which don''t contribute to hardness, soft water usually has low alkalinity and little buffering capacity.

Chalk: A biological limestone formed from shell debris
Chalk is a biological limestone derived from the tiny calcium carbonate shells of foraminifera and the calcareous remains of marine algae. It is soft, friable, porous, permeable and usually white to light gray in color. Chalk is widely known among the people of western Europe and a few other parts of the world because it is a bright white rock that can form vertical cliffs along shorelines.
