high concentration of salinity and phreeqc

[Scarlet]

there is a relation between the concentration of water in salts, and using phreeqc? we can use phreeqc when we have a high concentration of salts in the solution? and which data to choose?

If you have high concentrations, then pitzer.dat is the best database. However, pitzer.dat has a limited number of elements, no aluminum, and no redox.
