18.6: Occurrence, Preparation, and Properties of Carbonates

Figure 18.6.2 18.6. 2: The reaction of calcium carbonate with hydrochloric acid is shown. (credit: Mark Ott) Other applications of carbonates include glass making—where carbonate ions serve as a source of oxide ions—and synthesis of oxides. Hydrogen carbonates are amphoteric because they act as both weak acids and weak …

CaCO3: Definition, Preparation, Uses and Examples

CaCO3 is most notably limestone. It is a type of sedimentary rock that mainly consists of calcite and is the main component of eggshells, snail shells, seashells and pearls. Calcium Carbonate has medical use too as if as a calcium supplement or as an antacid. Though excessive consumption of calcium carbonate is hazardous and cause poor digestion.

Is CaCO3 Soluble in Water?

Calcium carbonate is not soluble in water as the lattice energy of the compound is very high in comparison to its hydration energy. Also, the solubility product for the CaCO3 compound is very low 3.3 X 10-9 indicating that this compound cannot dissolve in water. Mostly solubility increases with an increase in temperature but in the case of ...
