Chapter 4, Problem 4.93P

(a)

Interpretation Introduction

Interpretation:

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

$\text{Sn}\left(s\right)+2{\text{H}}^{+}\left(aq\right)\to {\text{Sn}}^{2+}\left(aq\right)+{\text{H}}_2\left(g\right)$

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:

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

$2{\text{H}}^{+}\left(aq\right)+{\text{H}}_2{\text{O}}_2\left(aq\right)+2{\text{Fe}}^{2+}\left(aq\right)\to 2{\text{Fe}}^{2+}\left(aq\right)+2{\text{H}}_2\text{O}\left(l\right)$
