React - pH sliding


Recommended Posts

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.)


Slide pH to H+

It looks like you don't have a constraint for the HCO3-, which is necessary for the higher pH range. Some constraints on other dissolved solutes (at a minimum Na and Cl) are going to be helpful as well for maintaining charge balance.
