Question

Using appropriate chemical reactions for illustration, show how calcium present as the dissolved bicarbonate salt in water is easier to remove than other forms of hardness such dissolved Calcium chloride​

Answer 1

Step-by-step explanation:

Calcium bicarbonate dissolved in hard water can easily be removed by heating the hard water . On heating , it decomposes to give calcium carbonate which is insoluble and therefore can be filtered out .

Ca( HCO₃)₂ = CaCO₃ + CO₂ + H₂O.

In this way hardness of water is removed .
