Chapter 24, Problem 125A

Interpretation Introduction

Interpretation: To interpret at which electrode the oxidation occurs in a voltaic cell and the charge on this electrode.

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 125A

The electrode at which oxidation occurs in the anode i.e., negatively charged.

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. An anode is interpreted as a negative electrode while the positive electrode is the cathode.

Conclusion

The electrode at which oxidation occurs in the anode i.e., negatively charged.
