Chapter 9.3, Problem 3QQ

Interpretation Introduction

Interpretation:

From the given options, the substance oxidized in a redox reaction has to be chosen.

Concept Introduction:

Redox reactions:

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