Chapter 19, Problem 83IAE

Interpretation Introduction

(a)

Interpretation:

Whether there is complete or incomplete separation between the ${\text{Cu}}^{2+}$ and ${\text{K}}^{+}$ ions take place needs to be determined.

Concept introduction:

In an electrochemical cell, chemical change is used to produce electricity. It uses electricity to produce a nonspontaneous reaction.

Electrolysis is the process in which a nonspontaneous reaction is driven by the application of electric energy.

The half-cell reaction with the lowest reduction potential reduces 1^st in electrolysis process.

When there has huge difference in the reduction potential values, ions can be efficiently separate out.

Interpretation:
