Step-by-step solution

In this method calculated amount of lime is added to hard water. It precipitates out calcium carbonate and magnesium hydroxide which can be filtered off(P)Mg(HCO3)2+2Ca(OH)2⟶2CaCO3↓+Mg(OH)2↓+2H2O\left(P\right)Mg{\left({HCO}_{3}\right)}_{2} + 2Ca{\left(OH\right)}_{2} ⟶ 2{CaCO}_{3} ↓ + Mg{\left(OH\right)}_{2} ↓ + 2{H}_{2}O
