Question

What is the Formula of the following silicate anion :

• A. $Si{O}_4^{4-}$
• B. $S{i}_2{O}_7^{6-}$
• C. $S{i}_2{O}_8^{6-}$
• D. $S{i}_3{O}_9^{6-}$

Answer 1

The correct option is B $S{i}_2{O}_7^{6-}$

Here two $Si{O}_4^{-4}$ attached at one oxygen center so formula of this one is $S{i}_2{O}_7^{6-}$.
