If i set a base matrix of compounds in a water system, is it possible to calculate the pH of set matrix?

They are here! with_CB.rea without_CB.rea

HI, i am having problems with some calculations in react, I am making a pH sliding of Zn++, i put the calculations with charge balance of Cl- and without charge balance. I get error for the charge balance, and the calculations stop for the pH of ~8.5 "Caution: molality of Cl- component forced negative by charge balance: -2.782e-007 *N-R didn't converge after 400 its., maximum residual = 4.83e+121, Xi = 0.5800 Cutting step size to find solution Residuals too large, 662-th interation -- Didn't wake up, abandoning path" For the sliding without the balance using react and even SpecE8 it can't compute from pH ~12.5 to ~13.8 but can compute for pH of 14. Why is that? I also find out that if i change the delxi from 0.01 to 0.001, making more dots the programs crushs and stops the compute arouth pH ~3.5 - ~6. Why is that? shouldn't it calculate the same for all? with_CB.rea without_CB.rea

Hello! I have done study of the sliding of pH from 1-14 for Zn, and i have some conclusion of spcecies. Now i need to make a study of those spcecies over time, things like concentrations, transformations,(...). Is it possible? And how? Thanks

I am having problems in react When make an input file to slide pH, the pH sliding ends around 3, sometimes arout 6 or 8.5. What should i do to make it go to 14 React> show Temperature is 25 C Thermo dataset: C:\Program Files\Gwb\Gtdata\thermo_wateq4f.dat Working directory: c:\users\andré\gwb Options: del 13-C Basis is: H2O 1 kg Zn++ 1 mol H+ 0 pH (Charge balancing disabled.) Reactants: Slide pH to H+

Hello , I need help because i want to make the Eh vs pH diagrams. As you can see i have made the diagrams but not the way i need them because i need to put water lines and keep the whole diagram, and a su can see i cant do it! Please Help!
