Question

Which one of the following anions is present in the chain structure silicates ?

• A. $S{i}_2{O}_7^{6-}$
• B. $(S{i}_2{O}_5^{2-}{)}_n$
• C. $(S{i}_2{O}_3^{2-}{)}_n$
• D. $S{i}_2{O}_4^{4-}$

Answer 1

Answer: (C)

$(S{i}_2{O}_3^{2-}{)}_n$

$(Si{O}_3^{2-}{)}_n$ has chain structure of silicates.
