Chapter 3, Problem 3.68E

Interpretation Introduction

Interpretation:

Balanced chemical equation for four possible reactions between ${\text{OH}}^{-}$ and ${\text{SiO}}_2$ has to be determined.

Concept Introduction:

Silicates are compounds that contain silicon and oxygen in tetrahedral ${\text{SiO}}_4^{4-}$ units. Silicates can be divided into many forms based on their bonded and shared oxygen atoms. In these tetrahedral ${\text{SiO}}_4^{4-}$ units, $\text{Si}-\text{O}$ bond is considered covalent bond.
