Chapter 22, Problem 111A

Interpretation Introduction

Interpretation: To interpret which process occurs at the cathode of the electrolytic cell and voltaic cell.

Concept introduction: A voltaic cell is beneficial in converting chemical energy to electrical energy. It consists of two half-cells where in one part oxidation takes place while in the other part reduction occurs.

Answer to Problem 111A

In an electrolytic cell as well as in a voltaic cell, reduction takes place at the cathode.

Explanation of Solution

An electrode is an electron carrier. It is categorized into two types which are as follows:

• Anode
• Cathode

Oxidation occurs at the electrode known as the anode while reduction takes place at the electrode known as the cathode.

The cathode is negatively charged in an electrolytic cell and a voltaic cell, the cathode is a positive electrode.

Conclusion

In an electrolytic cell as well as in a voltaic cell reduction takes place at the cathode.
