When a sample of hard water is passed through the layer of sodium zeolite resulting which of the following ions will not be present in the resulting sample of water obtained?

Options

A. `MG^(2+)` and `Ca^(2+)`
B. `Ca^(2+)` and `Na^(o+)`
C. `Mg^(2+)` and `CO_(3)^(2-)`
D. `CO_(3)^(2-)` and `Cl^(ɵ)`

Answer

A

Explanation

As `Na^(o+)` ions in sodium zeolites are replaced by `Ca^(2+0`, and `Mg^(2+)` ions present in hard water, these two ions will not be present.
