1.	Which statement about zeolite is false ?A. They are used as cation exchangersB. They have open structure which enables them to take up small moleculesC. Zeolites are aluminosilicates having three dimensional networkD. None of the `SiO_(4)^(4-)` units are replaced by `AlO_(4)^(5-)` and `AlO_(6)^(9-)` ions in zeolites.
Answer» Correct Answer - D Zeolites have `SiO_(4)^(4-)` and `AlO_(4)^(5-)` tetrahedron, linked together in a three dimensional open structure in which four or six membered rings predominate. Due to open chain structure, they have cavities and can take up water and small molecules.
