Applied Chemistry : Theory And Practice
(2) Hehner's Method: Boiling removes temporary hardness by converting
bicarbonates into insoluble carbonates and hydroxides [reactions 3.26 and 3.27]
which are removed by filtration, thereby causing an equivalent decrease in
alkalinity.

Note: The two types of water hardness are temporary hardness and permanent
hardness. Temporary hardness is also known as carbonate hardness (hardness
that can be removed by boiling); permanent hardness is also known as ...
Hardness of water is of two types : temporary hardness and permanent hardness
Temporary hardness : When hardness of water is due to the presence of soluble
bicarbonates of calcium and magnesium, it is called temporary hardness.

2 (CaHCO3)2 soluble 5:9 Bicarbonate hardness is also referred to as temporary
hardness, because it may be removed by heating the water. This reverses the
reactions, which put the calcium and magnesium into solution (Eqs. 5.10 and
5.11).
Martin B. B. Hocking, 2006
The bicarbonate salts on heating, decompose to give water insoluble carbonates
and hence are said to impart only temporary hardness. Ca (HCO,)2 CaCO, +
