How is zeolite (permutit) regenerated for further use in the ion-exchange method?

Options

  1. ABy heating it to a high temperature
  2. BBy treating it with an aqueous sodium chloride solution
  3. CBy adding more zeolite to it
  4. DBy filtering it

Correct answer

B. By treating it with an aqueous sodium chloride solution

Step-by-step solution

Zeolite (permutit) is regenerated for further use in the ion-exchange method by treating it with an aqueous sodium chloride solution, which replaces the adsorbed hardness ions with sodium ions.
