Chapter 20.4, Problem 20.6.1PE

Interpretation Introduction

Interpretation: The standard reduction potential for the given reaction is to be calculated.

Concept introduction: In voltaic cell, the oxidation reaction takes place at anode and reduction takes place at cathode. Thus, $E_{\text{red}}^{\circ }$ is the reduction potential of a substance. The positive value of $E_{\text{red}}^{\circ }$ indicates the substance is more readily reduced and negative value of $E_{\text{red}}^{\circ }$ indicates that the substance is more readily oxidized.

To determine: The standard emf of the given voltaic cell.
