PHREEQC reaction



Mr. Parkhurst,

I am working with PHREEQC and using the LLNL database. I have a reaction
SiO2 + H20 = H2SiO3
along with the log k. I tried inputing this information as one of the phoses for inverse modeling, but I got an error message saying that PHREEQC didn't recoginize H2SiO3. I know that LLNL has SiO2 as the master species for Si. I was wondering how to input H2SiO3 as a master species. I tried entering a new master species before, but it seemed like I entered it incorrectly, because the program still didn't recognize it. If you could please help me out with this matter, I would greatly appreciate it.


Thank you for your time,
Elizabeth Bryant
