Carbonate de calcium

Le carbonate de calcium (CaCO 3) est composé d'un ion carbonate (CO 3 2-) et d'un ion calcium (Ca 2+), sa masse molaire est de 100 g/mole. C'est le composant principal du calcaire et de la craie, mais également du marbre. C'est aussi le principal constituant des coquilles d'animaux marins, le corail et des escargots.
