Question #0c67e

Answer 1

An `E^0`-pH diagram, also known as a Pourbaix diagram, is a chart used to record the various stages of an element in different pH levels and voltages.

Explanation:

Here is the `E^0`-pH diagram for Iron:

This is important for being able to record changes in an element such as Iron. For example, if Iron was in a pH of 2 and received a voltage of -1, it would still remain Iron. However, if the voltage was raised to 1. We can see that Iron has changed its state to `Fe^(3+)`.

Using Pourbaix diagrams makes cataloging the changes of elements much easier and allows for these elements to be easily manipulated for future experiments.
