Chapter 17, Problem 25AE

Interpretation Introduction

Interpretation:

Elements that gets oxidized and reduced in below reaction have to be determined.

  $4{\text{KNO}}_{\text{3}}\left(s\right)+7\text{C}\left(s\right)+\text{S}\left(s\right)\to \left[\begin{array}{c}3{\text{CO}}_{\text{2}}\left(g\right)+3\text{CO}\left(g\right)+2{\text{N}}_{\text{2}}\left(g\right)\\ +{\text{K}}_{\text{2}}{\text{CO}}_{\text{3}}\left(s\right)+{\text{K}}_{\text{2}}\text{S}\left(s\right)\end{array}\right]$

Concept Introduction:

Oxidation process represents loss of electrons by increase in oxidation state of elements. Reduction process represents gain of electrons by decrease in its oxidation state. Oxidation numbers are part of system that is formed to track electrons in reaction.
