I am working with wateq4f.dat database of PHREEQC program. How to calculate each of the chemical element species percentage? For example, what will be Al(OH)4-, Al(OH)2+, Al(OH)3 percentage from Al? Can I calculate it?
Unfortunately, from what it seems, PHREEQC doesn't have a tool that will allow you calculate each of the chemical element species percentage. You can read about all features and options of the application in the user guide that you can find in the Help menu:
