The usual method for the preparation of the carbonates of the alkali and alkaline earth metals is by reaction of an oxide or hydroxide with carbon dioxide. Other carbonates form by precipitation. Metal carbonates or hydrogen carbonates such as limestone (CaCO 3 ), the antacid Tums (CaCO 3 ), and baking soda (NaHCO 3 ) are common examples.

The fact that the calcium ion is of approximately the critical radius leads to the ability of calcium carbonate to crystallize in either system. This trait explains the polymorphism of calcite and aragonite, both of which possess the chemical formula CaCO 3 but which crystallize according to the differing rhoohedral and orthorhoic crystal systems.
