Chapter 8, Problem 8.46E

Interpretation Introduction

Interpretation:

The value of $K_{\text{w}}$ by combining the proper half-reactions for given reaction is to be stated. Whether the answer makes any sense or not is to be stated.

Concept introduction:

$K_{\text{w}}$ is the ionic product of water and its relation with $E_{\text{cell}}^{°}$ is given below.

$E_{\text{cell}}^{°}=\frac{RT}{f}\ln K_{\text{w}}$

$E_{\text{cell}}^{°}$ can be calculated using the standard potentials for the half-cell reaction. Thus by combining proper half cells, $K_{\text{w}}$ can be calculated.
