jbeam Posted May 18, 2021 Share Posted May 18, 2021 I'm attempting to calculate speciation in a complex brine system and continually receive the ion strength out of range error. The error seems to be focused around the interactions of EDTA4- with Ca2+ and Mg2+. Oxalate also seems to have this same issue. If I swap the EDTA concentration for the species we expect to dominate, CaEDTA2-, this just moves the error to another species in the calculation. The model seems to give accurate data when EDTA and Oxalate are removed from the calculations. Quote Link to comment Share on other sites More sharing options...
