React pH calculation


Recommended Posts



I'm running some water-rock reactions using REACT, and I'm puzzled why the pH that GWB calculates (11.682 in one particular case) is not quite the same as -log( [H+] ), where [H+] in the same case is 2.508e-12, which yields a pH of 11.601.


Should I not be paying attention to the sig figs? I was just curious as to how GWB calculates pH, if not by -log( [H+] )
