Chapter 4, Problem 4.92P

(a)

Interpretation Introduction

Interpretation:

The oxidizing agent and the reducing agent in the following reaction are to be determined.

$5{\text{H}}_2{\text{C}}_2{\text{O}}_4\left(aq\right)+2{\text{MnO}}_4^{-}\left(aq\right)+6{\text{H}}^{+}\left(aq\right)\to 2{\text{Mn}}^{2+}\left(aq\right)+10{\text{CO}}_2\left(g\right)+8{\text{H}}_2\text{O}\left(l\right)$

Concept introduction:

A redox reaction is a type of reaction that involves the change in oxidation number of a molecule, atom or ion changes due to the transfer of an electron from one species to another.

An oxidizing agent is a substance that oxidizes another species and itself gets reduced in a chemical reaction. A reducing agent is the one that reduces another species and itself gets oxidized in a chemical reaction.

(b)

Interpretation Introduction

Interpretation:
