No, I can't use this approach for my experiments, I have special conditions that don't allow me to measure the pH for a few minutes, I only have a few seconds to do it. I can still do it, but I know that the measurement won't reflect the reality of the solution during my experiment. Yes, I set HCO3- as the equilibrium charge and see how much I need to reach equilibrium Best regards, Jerome

Hello Jia, Same question, how can I calculate the alkalinity with GWB knowing that I can't do the titration? I am doing complicated experiments where it is impossible for me to measure the alkalinity right after the experiment. I still can have the pH, TDS and the chemical composition. I am trying by using HCO3- to reach the charge balance but I wonder if there is any other method to find the alkalinity Thanks for reading
