m.scharrer Posted August 11, 2017 Share Posted August 11, 2017 Hello Admin, if i am interested in a fO2-pH Predominance diagram of Fe of a speculated fluid with for example the following parameters: H2ASO4 as As = 50 mg/l SO4-- as S = 50 mg/l Fe++ as Fe = 10 mg/l Na++ = 39.34 g/kg Cl- = 60.66 g/kg T = 150 °C ive been using GSS to calculate the activities of specific species which i applied in Act2. For the GSS calculations i did not input any pH value since it will be my x-axis on my diagram. Now my question is if that is the correct procedure since of course using specific pH values in GSS gives me different activities of my species and thus greatly altering the predominance diagram in the end? For what pH or in general for what terms do the activities calculated in GSS apply if no pH is entered? Sincerely Manuel Quote Link to comment Share on other sites More sharing options...
