Best Answer

Calcium carbonate is an ionic salt, formed from the cationic calcium (II) and the anionic carbonate ion CO32-. It is found naturally in limestone and in seashells.

vCalcium carbonate reacts with acids, releasing carbon dioxide:

v

vCalcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate.

CaCO3 + CO2 + H2O → Ca(HCO3)2

This reaction is important in the erosion of carbonate rocks, forming caverns, and leads to hard water in many regions.

Water with a large amount of dissolved calcium is hard water.
