Closely examine Figure 14.1 and explain why no reaction occurs in part d.

Because copper ions have a greater affinity for electrons than zinc ions.

Because zinc ions have a greater affinity for electrons than copper ions.

Because the temperature is too warm for a reaction to occur.

Interpretation Introduction

Interpretation:

The reason behind a reaction not occurring in part d of the given figure is to be explained.

Concept Introduction:

Oxidation is the addition of an electronegative element and the removal of an electropositive element in a chemical reaction.

Reduction is the addition of an electropositive element and the removal of an electronegative element in a chemical reaction.

A chemical reaction in which oxidation process and reduction process takes place simultaneously is called a redox reaction.

An oxidizing agent is a substance that has the capacity to oxidize another substance, and to get reduced, in a chemical reaction.

A reducing agent is a substance that has the capacity to reduce another substance, and to get oxidized, in a chemical reaction.

Explanation of Solution

The reaction will not take part in part d of the given figure because the copper strip is dipped in the zinc solution. Zinc is more reactive than copper. Highly reactive metals have a tendency to lose electrons easily. So, their electron affinity is low. The less reactive metals have a high electron affinity. So, they have a tendency to gains electrons. No loss or gain of electrons occurs.

Therefore, no reaction takes place...
