Chapter 20.3, Problem 20.4.1PE

Interpretation Introduction

Interpretation: The description that correctly defines the process occurring in half-cell containing the $\text{Cu}$ electrode and ${\text{Cu}}^{\text{2+}}$ solution is to be determined.

Concept introduction: In voltaic cell, the anode is an electrode where oxidation reaction takes place and cathode is an electrode where the reduction reaction takes place. As the reaction proceeds, there is a loss in the mass of anodic rod while the cathodic rod gains mass. The purpose of attaching a salt bridge is to maintain electro neutrality by supplying cations to the cathode half-cell and anions to the anode half-cell.

To determine: The description that correctly defines the process occurring in half-cell containing the $\text{Cu}$ electrode and ${\text{Cu}}^{\text{2+}}$ solution.
