Hi everyone,
I have a question to ask.
Can the pitzer database be considered reliable up to what concentration exemple in molality?

I can't answer that in general; it depends on the system that you have. Data for most strong electrolytes are fit to several molal, but you would need to go back to the original sources of Pitzer's papers and Harvie, Moeller, and Weare to consider the electrolytes of your system.

Thank you very much Sir.Parkhurst.
My system has Na-K-Mg-Cl-S04-H2O, you can think of it, as sea water but without Ca. I read a paper by Harvie and Weare , if I'm not mistaken the concentration is limited to 6 M.
The main data I am interested in is the water activity coefficient for this solution.
