    The three-dimensional lattice of zeolites consists of:

    A)  \[{{[S{{i}_{2}}{{O}_{7}}]}^{6}}\]

    B)                         \[[Si{{O}_{3}}]_{n}^{2n-}\]

    C)  \[[{{S}_{2}}{{O}_{5}}]_{n}^{2n-}\]          

    D)         only\[Si{{O}_{2}}\]

    E)  \[{{[AlS{{i}_{3}}{{O}_{8}}]}^{-}}\]

    Correct Answer: E

    Solution :

    Zeolites are microporous aluminosilicates having general formula My\[{{M}_{x/n}}{{[Al{{O}_{2}}]}_{x}}\] \[[Si{{O}_{2}}].M{{H}_{2}}O\]The three dimensional lattice of zeolites consists of\[{{[AlS{{i}_{3}}{{O}_{8}}]}^{-}}\].
