Vedclass · Answer

(D) Zeolites are aluminosilicates with a three-dimensional honeycomb-like structure. $1$. They act as water softeners because they function as ion exchangers,replacing $Ca^{2+}$ and $Mg^{2+}$ ions in hard water with $Na^+$ ions. $2$. They act as catalysts in shape-selective catalysis due to their porous structure,such as $ZSM-5$ which converts alcohols to gasoline. $3$. They act as cation exchangers by exchanging their sodium ions for other cations. Since zeolites exhibit all these properties,the correct answer is $D$.
