Temporary hardness is due to dissolved calcium (or magnesium) hydrogen carbonate Ca(HCO3)2, it can be removed by boiling the water, when the hydrogen carbonate ions decompose forming insoluble calcium (or magnesium) carbonate: Ca(HCO 3) 2 –> CaCO 3 + CO 2 + H 2 0.
Loevenhart and Crandall 1 have recently suggested the use of calcium carbonate in the treatment of the gastric hyperacidity syndrome. The reason for suggesting it was that calcium carbonate is a very insoluble substance and that the suspension is apparently neutral in reaction, although it has a high neutralizing power for acids.

Calcium bicarbonate is not a naturally occurring solid, but it does form in water when calcium, carbonate and bicarbonate ions are dissolved with carbon dioxide. This commonly happens within rivers, streams, lakes and well water because of the water's exposure to the air and its contact with rocks and sediment that contain minerals and metals.
