MCQ
A cyclic skeleton of silicon and oxygen can constructed by the silicate ion composition
  • A
    $Si_2O_7^{4-}$
  • B
    $Si_2O_5^{2-}$
  • $SiO_3^{2-}$
  • D
    $SiO_4^{4-}$

Answer

Correct option: C.
$SiO_3^{2-}$
c
Cyclic silicates contain $\left( SiO _3\right)_{ n }^{2 n -}$ ions which are formed by linking three or more tetrahedral $SiO _4^{4-}$ units cyclically. Each unit shares two oxygen atoms with other units.
