Question

BaTi $[S{i}_3{O}_9]$ is a class of

• A. orthosilicate
• B. cyclic silicate
• C. chain silicate
• D. sheet silicate

Answer 1

Answer: (B)

The primary unit of BaTi( $S{i}_3{O}_9$ ) or $\left(S{i}_3{O}_9^{6-}\right)$ is ${\left(Si{O}_3\right)}^{2-}($ as $n=3)$ Thus, it is formed by sharing of two oxygen per Si atom and results in the formation of cyclic silicate.
