Calcium Chloride and Sodium Carbonate

CaCl2 + Na2CO3 → CaCO3 + 2NaCl

Genel Bakış

Calcium chloride reacts with sodium carbonate to form insoluble calcium carbonate precipitate and sodium chloride. This is the basis of the water softening process where dissolved calcium ions are removed as insoluble carbonate. The white precipitate settles as chalk-like material.
