Hello,
Im really new to this. I am basically trying to replicate this Eh pH diagram as a learning process:
But i cant figure out how.
This is my graph i made with GWB student
And the basis
- What do the horizontal blue dotted lines represent on my graph?
- Why does my GWB graph show the water limits? when i try to turn on the water limits i get a error: reaction for H2(g) is missing; can not plot water limit. I am using the thermo_minteq data set for all the lanthanides.
- Why is my lanthanum free ion off on the pH so much? Am i not correctly inputting the carbonate. I added CO3-- in the 'in the presence of' section, is this correct? Or should i make it swap basis entry with La+++ as the diagram species?
- i guess the main thing is im not sure how to add other ligands such as carbonates, hydroxides, fluorides, etc. When i try to add them in they dont seem to work properly or resemble any of the other graphs with the same mineral system.
Thank you so much for any help,
Thanks
