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

Text Solution

Verified by Experts

Yes, it is possible on boiling, `Mg(HCO_(3))_(2))` will readily decompose to form a precipitate of `MgCO_(3)` which can be removed by filtration.
`Mg(HCO_(3))_(2) overset("Heat")to underset("ppt")(MgCO_(3))+H_(2)O+CO_(2)` As a result, water will become free from temporary hardness.
