Chapter 8, Problem 8.53E

Interpretation Introduction

Interpretation:

The oxidation of $\text{Fe}$ (the major reaction in the corrosion of iron) to ${\text{Fe}}^{2+}$ is promoted by high $\text{pH}$ (basic solutions) or low $\text{pH}$ (acidic solutions) is to be predicted by using the cell from Example 8.8.

Concept introduction:

The $\text{pH}$ scale measures the concentration of the hydrogen ions. The acidic solutions have $\text{pH}$ less than $7$ whereas the basic solutions have $\text{pH}$ more than $7$.
