Carbon dioxide and lime - OASE
If carbon dioxide is withdrawn from the water, insoluble lime and carbon dioxide form until the balance is restored. Insoluble lime is recognised as a white precipitation that is familiar as limescale. Since water when heated loses the ability to store lime in dissolved form, lime precipitates as limescale.
