Procedure

The main cause of hard water is generally dissolved calcium bicarbonate (Ca(HCO3)2). In limestone or chalk regions, calcium hydrogencarbonate is formed by the action of dissolved carbon dioxide on calcium carbonate. In some areas, hardness also results from dissolved calcium sulfate (CaSO4).
