उत्तर
To remove temporary hardness by boiling: Bicarbonate changes to insoluble carbonate and water becomes soft.
\[\ce{\underset{\text{calcium bicarbonate in hard water}}{Ca[HCO3]2}->[Boil]\underset{\text{Cal.carbonate}}{CaCO3}↓ + CO2 +\underset{\text{water}}{H2O}}\]
\[\ce{\underset{\text{Magnesium bicarbonate}}{Mg[HCO3]2}->[Boil]\underset{\text{Magnesium bicarbonate}}{MgCO3↓} + CO2 + H2O}\]
