Pourbaix diagram question

[NathanHussey]

Hi,
I am confused about construction of pourbaix diagrams. Simply, why are oxidizing conditions more positive & reducing conditions more negative?

Seems different to the electrochemical series, where reducing elements (or more cathodic) are more positive.

Thanks in advance for your clarifications.

it is by convention. The + and - are by definition.

= = = = = = = = = = = = = = = = = = = =
