✔ WHAT CAUSES HARDNESS OF WATER?
➡ Hardness of water is due to the presence of salts of calcium and magnesium in it.
✔ HOW CAN TEMPORARY HARDNESS BE REMOVED?
➡ It can be removed by boiling.
✔ REMOVAL OF Ca(HCO3)2 :
➡ The soluble Calcium bicarbonate present in the water decomposes to form insoluble Calcium Carbonate along with Carbon dioxide (CO2) and Water (H2O).
➡ The insoluble Calcium Carbonate thus formed are removed from boiled water by filtration, leaving behind soft water which is free from salts of calcium.
==================================
So, Boiling (Heat) is required for the removal of Ca(HCO3)2.
