Vedclass · Answer

(D) Zeolites are hydrated sodium aluminosilicates which have a porous structure. They are used as water softeners because they exchange $Na^+$ ions with $Ca^{2+}$ and $Mg^{2+}$ ions present in hard water. They act as cation exchangers due to their ion-exchange properties. They are also widely used as shape-selective catalysts in the petrochemical industry (e.g.,$ZSM$-$5$). Therefore,all the given statements are correct.
