Which one of the following statements about
the zeolites is false ?
(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 SiO⁴⁻₄ units are replaced by
AlO⁵⁻₄ and AlO⁹⁻₆ ions in zeolites

Answer 1

Answer:

the answer is as follow

Explanation:

c

if you want right answer of this statement thanks me

Answer 2

Answer:

Heyaa✌️✌️

In zeolites, some of the the Si4+ ions may be replaced by Al3+ . This results in unbalanced anionic charge. To maintain electrical neutrality, positive ions must be introduced.

Thus, the statement B is incorrect.

Hope it helped you.
