Chapter 1, Problem 36Q

Interpretation Introduction

Interpretation:

• The flowchart that illustrates the reactions required to convert ${\text{SiO}}_{\text{2}}$ sand into high-purity silicon has to be drawn.
• About what happens to the waste products that are generated in each step has to be discussed.
• The sustainability of this process has to be found.

Concept Introduction:

${\text{SiO}}_{\text{2}}$ is known as silica or silicic oxide or silicon dioxide. It is the major constituent of sand and most commonly found in nature as quartz and $\text{Si}$ is known as silicon which is widely used for electronic devise because of one of its most important properties that it is a semiconductor.
