Chapter 20.5, Problem 20.10.1PE

Interpretation Introduction

Interpretation: The standard reduction potential of the given half-reaction is to be determined.

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 that the substance more readily reduces and negative value of $E_{\text{red}}^{\circ }$ indicates that the substance more readily oxidizes.

To determine: The standard reduction potential of the given half-reaction.
