Chapter 21, Problem 21.119SP

Interpretation Introduction

Interpretation:

To write a balanced equation for the preparation of ${\text{GeS}}_{\text{2}}$ from tetraethoxygermane, $\text{Ge}{\left({\text{OCH}}_{\text{2}}{\text{CH}}_{\text{3}}\right)}_{\text{4}}$ , and H₂S in an organic solvent. GeS₂ is a nonoxide ceramic accessible by the sol-gel method.

Concept introduction:

Sol-gel method is a method for production of solid materials from small molecules. Sol-gel method is useful for production of metal oxides i.e. oxides of silicon or titanium.

Ceramics are inorganic, non-metallic, non-molecular solids, including both crystalline and amorphous materials. Ceramics have higher melting points, they are stiffer, harder, and more resistant to wear and corrosion than metals.

To write:

A balanced equation for the preparation of GeS₂ from tetraethoxygermane, Ge(OCH₂CH₃)₄, and H₂S in an organic solvent.
