Which one of the following statements about the zeolite is false?

Multiple Choice Options

  • A They are used as cation exchangers.
  • B They have open structure which enables them to take up small molecules.
  • C Zeolites are aluminosilicates having three dimensional network.
  • D Some of the SiO44−SiO_4^{4-} units are replaced by AlO45−AlO_4^{5-} and AlO69−AlO_6^{9-} ions in zeolites.

Step-by-Step Verified Solution

Zeolites are alumino silicates having three dimensional open structure in which four or six membered ring predominates. Thus, due to open chain structure, they have cavities and can take up water and other small molecules.
