I’m new to Pourbaix diagrams, and when looking for example at Fe alone generated by the Materials Project, I notice that the temperture is not given. Is this at 25 °C and 1 atm? Some other conditions? Also, I’m assuming the top orange line is oxygen stability, and the bottom orange line is H2 stability, but that took me a bit of time to figure out (again, these diagrams are new to me).
The diagrams are computed at STP (300K and 1 atm) - if you need guidance on how to use / interpret the app, our docs have a detailed rundown of the pourbaix app!
Great, thank you!
