Chapter 17, Problem 93QRT

(a)

Interpretation Introduction

Interpretation:

The species which is oxidized and which is reduced have to be identified.

Concept Introduction:

A reducing agent is a reacting species in the reaction that reduces another reacting species.  A reducing agent itself gets oxidized when reacts with another species.  The reducing agent donates electrons.  An oxidizing agent is a reacting species in the reaction that oxidize another reacting species.  An oxidizing agent itself gets reduced when it reacts with another species.  The oxidizing agent accepts electrons.

(b)

Interpretation Introduction

Interpretation:

The oxidizing and reducing agent in the voltaic cell have to be identified.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction
