Noam_at_large

mschock, Thank you for the reference. I was able to find a more complete representation with the minteq database. I'm interested in your suggestion of presenting multiples of the same solid phase. Could you share a script where you did so? Even if not lead, I can adapt it. I'm just real new to this software and found it more effective to start from functional scripts than from scratch.

I'm attempting to replicate the chart for the Pb-H2O-CO2 Eh-pH system. I've found two charts in literature that are not quite in agreement, but they include Pb(0), PbO2, Pb(OH)x, PbO3-, etc. Was able to only get Pb(2+) and PbCO3 in Act2. Please advise. EhpH_Pb_co2.ac2

In Plot Area, what does it mean to bubble in "Mineral Fields"? Do Mineral Fields show more stable species? They seem to be stable in much wider conditions. Are the mineral fields even relevant to me in an electrolysis project? I ask because the paper I read showed SnO2 / Sn, which shows up with Mineral Fields selected. Where as having them unselected I get the following

Thallium and Bismuth do not appear to be selectable as ions (for the purpose of an Eh-pH diagram, in Act2). I tried cycling through the other databases in File/Preferences. How would I access these metals?
