  1. OK, I was able to sway H2 for O2 and when I swaped B(OH)4- or B(OH)3 I got outputs for both species but it made me define the pH. Is there a way to make the program calculate the pH simply based on input concentrations and charge balance? When I tried to swap for the other borate species it indicated they must not be in database at my temperature so I am guessing the high temp borate model is only these two species. I then proceeded to add Ca, Al, Si and a few other species to get mineral precipitates. I was happy to see that the calcium hydrolysis product appeared in the output without swapping. I could swap Al for a mineral and get that precipitate. However, there are multiple possible Al precipitates and I could only swap for one. Is there a way to input multiple precipitates and have the program calculate which ones will actually precipitate rather than being limited to only one precipitate for a given element?
  2. OK, I am dense. I just purchased GBW Essentials and am trying to get started on a few simple calculations. As a simple starting example, I am trying to input 5500 mg/kg B(OH)3, 3 mg/kg Li, 300C and would like to calculate the pH and the species distributions for boron and lithium. When I input these on the SpecE8 input screen, the output shows little more than my input info. How do I get it show the concentrations of each borate and lithium species and the at-temperature pH? Second item: How do I input aqueous hydrogen since it is not on the SpecE8 input screen? Thanks for helping a rookie get started,
