Le carbonate de calcium est très faiblement soluble dans l’eau pure (de l'ordre de 15 à 20 mg · L-1 à 25 °C), mais soluble dans l’eau chargée de dioxyde de carbone. Or la solubilité des gaz dans l’eau augmente avec la pression et, contrairement à celle de la plupart des solides, diminue lorsque la température augmente.
