Is it possible to remove completely by boiling the temporary hardness due to Mg(HCO_(3))_(2) ?

Answer»

SOLUTION :Temporary hardness of `H_(2)O` due to `Mg(HCO_(3))_(2)` can be completely REMOVED by boiling because soluble `Mg(HCO_(3))_(2)` is converted into INSOLUBLE `MgCO_(3)` which can be removed by filtration
`underset("(Soluble)")(Mg(HCO_(3))_(2)) OVERSET("BOIL")to underset("(Insoluble)")(MgCO_(3) darr) + CO_(2) uarr + H_(2)O`
