Temporary hardness of water is removed in Clark's process by adding

Options

  1. Acaustic soda
  2. Bcalgon
  3. Cborax
  4. Dlime

Correct answer

D. lime

Step-by-step solution

The temporary hardness of water is due to the presence of bicarbonates of Ca and Mg . This may be removed by Clark's process. In this process, addition of calculated quantity of lime causes precipitation of CaCO ₃ as array r Ca ( HCO ₃ )₂+ Ca ( OH )₂ 2 CaCO ₃ +2 H ₂ O and Mg ( HCO ₃ )₂+2 Ca ( OH )₂ 2 2 CaCO ₃ + Mg ( OH )₂+2 H ₂ O array
