It is possible to remove completely the temporary hardness due to `Mg(HCO_(3))` by boiling?

Text Solution

Verified by Experts

Temporary hardness of water 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 easily removed by filtration.
`underset("Soluble")(Mg(HCO_3)_2) overset("Boil")to underset("Insoluble")(MgCO_3)+ CO_2 + H_2 O`
