Chapter 23, Problem 17QP

Interpretation Introduction

Interpretation:

The metals that will get deposited and dissolved in solution and the ones that will remain unaffected are to be determined.

Concept Introduction:

Electrolysis is an electrochemical process by which the current passes from one electrode to another in an ionized solution, which is an electrolyte.

Electrolysis of copper involves the transfer of copper atoms from an impure copper anode to a pure copper cathode. The electrolyte is a solution of copper(II) sulfate.

According to the electrochemical series, the metals $\text{Ag, Pt, and Au}$ have a higher reduction potential than copper and will get reduced and deposited.

The metals $\text{Fe, Zn, Co, and Pb}$, whose reduction potential is less than copper will not get reduced and remain unaffected.
