Q. Statement 1: Cyclic silicates and chain silicates have the same general molecular formula.
Statement 2: In cyclic silicates, three corners of each $SiO _4$ tetrahedron are shared while in chain silicates only two are shared with other tetrahedron.

Solution:

Cyclic silicate and chain silicate both have same general formula $\left( SiO _3\right)^{2-}$. In cyclic silicates oxygen atom is shared per tetrahedral and the basic unit is $Si _3 O _9^{6-}$ chain silicates involve sharing of two oxygen atoms by each tetrahedral having basic unit $\left( SiO _3\right)_n^{2 n-}$.
