When Zeolite, which is hydrated sodium aluminium silicate is treated with hard water, the sodium ions are exchanged with which of the following ion(s)? (i) H^+ ions (ii) Mg^2+ ions (iii) Ca^2+ ions (iv) (SO_4)^2- ions

Answer: Option ii) & iii)

Because of this, when zeolite, which is sodium aluminium silicate, reacts with hard water, the sodium ion of zeolite is swapped for calcium and magnesium ions.
