Question

Formula of Pyro silicic acid:

• A. $H_{2}S{i}_4{O}_9$
• B. $H_{4}S{i}_2{O}_6$
• C. $H_{4}S{i}_3{O}_8$
• D. $H_{6}S{i}_2{O}_7$

Answer 1

Answer: (D)

$H_{6}S{i}_2{O}_7$

Hydrated Silica is a form of silicon dioxide, which has a variable amount of water in the formula. It is also known as silicic acid, a term usually used for its form dissolved in water. $H_{6}S{i}_2{O}_7$ is chemical formula of pyro silicic acid. Chemical Formula: $Si{O}_{2n}{H}_{2}O$.
