Thank you Brian.

Thanks Brian. This was helpful.So in new model there is no checkbox for "water limits" as its written in minteq database: "Visual Minteq does not include H2(g), thus the config->options->"water limits" checkbox for GWB programs Act2 and Tact needs to be unchecked when using this dataset" I have another question related to GtPlot. In Eh-ph diagram plots some of the species overwrite each other. I have attached one of such plots. Is there a way to separate them? Thanks again. Regards, Kawal Eh-Ph diagram.pdf

Thanks for quick reply. Attached is modified minteq database. thermo_minteq(H2g).zip

How to use thermo_minteq database in Act to make proper Eh-pH diagram? I tried using it. It gave me msg saying "Reaction for H2(g) is missing, cannot plot water limit" After i said ok it gave me plot but without water limits. also i added H2(g) in minteq database, still its showing me same msg. Can you please help me with this Thanks Kawal
