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

1. They are used as cation exchangers
2. They have open structure which enables them to take up small molecules
3. Zeolites are aluminosilicates having three dimensional network
4. Some of the SiO4⁴⁻ units are replaced by AlO4⁵⁻ and AlO6⁵⁻ ions in zeolites

Correct answer: Some of the SiO4⁴⁻ units are replaced by AlO4⁵⁻ and AlO6⁵⁻ ions in zeolites

Solution

Zeolites are aluminosilicates where some SiO4⁴⁻ units are replaced by AlO4⁵⁻ ions, but not AlO6⁵⁻ ions. The statement mentioning AlO6⁵⁻ is incorrect.
