Chapter 20, Problem 63A

Interpretation Introduction

Interpretation:

The movement of copper ions in the electrolyte solution is to be explained.

Concept introduction:

In an electrolytic cell, the ions present in the solution move towards the anode and cathode depending on their respective charges and get discharged.

Answer to Problem 63A

In the given electrolytic cell, the copper ions present in the solution move towards the cathode because they are positively charged, and the cathode is negatively charged so they get discharged at the cathode.

Explanation of Solution

In the electrolytic cell, the copper ions being positively charged move towards the negatively charged cathode and get reduced to copper metal as a deposit on the cathode with the following reaction occurring at cathode:

$C{u}^{2+}+2e^{-}\to Cu$

Conclusion

The copper ions in the solution move towards the cathode and get discharged and deposited at the cathode surface.
