Chapter 9.3, Problem 4QQ

Interpretation Introduction

Interpretation:

Substance which is reduced in the given redox reaction ${\text{CO+H}}_{\text{2}}\text{O}\to {\text{CO}}_{\text{2}}{\text{+H}}_{\text{2}}$ has to be shown.

Concept Introduction:

Redox reactions:

It is a type of reaction in which both oxidation and reduction happens simultaneously.  One gets oxidized and one gets reduced.

Example:

${\text{Zn(s)+2H}}^{\text{+}}\text{(aq)}\to {\text{Zn}}^{\text{2+}}{\text{(aq)+H}}_{\text{2}}\text{(g)}$

Zn is oxidized and hydrogen is reduced here.
