In zeolites,any $SiO_4^{4-}$ units are not replaced by $AlO_4^{5-}$ and $AlO_6^{9-}$ ions.

Vedclass · Answer

(D) Zeolites are aluminosilicates with a three-dimensional network structure in which some silicon atoms are replaced by aluminum atoms,giving the framework a negative charge. This framework is represented as $Al_xSi_{1-x}O_2$. Therefore,the statement that $SiO_4^{4-}$ units are not replaced by $AlO_4^{5-}$ ions is incorrect,as this replacement is the fundamental reason for their ion-exchange properties.

Which of the following statements about zeolites is incorrect?
