Exhausted permutit does not contain .......ion
Options
- ANa ⁺
- BMg ²⁺
- CAl ³⁺
- DSi ⁴⁺
Correct answer
A. Na ⁺
Step-by-step solution
Permutit or zeolite is the aluminosilicate of sodium. It is used to remove hardness of water. It converts insoluble salts of Ca ²⁺ and Mg ²⁺ into soluble zeolites. It exchange these ions with Na ⁺ and water becomes soft. Thus exhausted permutit does not contain Na ⁺ ions.
