उत्तर
Temporary hardness—
By Boiling— This method helps to remove only the temporary hardness of water. When temporary hard water is boiled, the bicarbonates of calcium and magnesium break up to form their insoluble carbonates.
These can be filtered out so that water becomes soft
\[\ce{\underset{\text{(soluble calcium bicarbonate}}{Ca(HCO3)2}->[boild]\underset{\text{(ppt)(calcium carbonate)}}{CaCO3}+\underset{\text{(water)}}{{H2O}} + \underset{\text{(carbon dioxide)}}{CO2(g)}}\]
