Temporary hardness of water is removed in Clark's process by adding
- A caustic soda
- B calgon
- C borax
- D lime
Answer & Solution
Correct Answer
(D) lime
Step-by-step Solution
Detailed explanation
The temporary hardness of water is due to the presence of bicarbonates of \(\mathrm{Ca}\) and \(\mathrm{Mg}\). This may be removed by Clark's process. In this process, addition of calculated quantity of lime causes precipitation of \(\mathrm{CaCO}_3\) as…
