How to define the PH value for my species ????
HI~~
My electrolysis reactions are below: Cathode: 2OH- --> 0.5 O2 + H2O Anode: 2H2O ---> H2 + 2OH- Initially, there are H2O + OH- in my solution. The problem is that how can I define the PH of the OH- in the solution? Or it can be translated by another form like mass or another. Can somebody help me~ Thank you. |

pH is a derived quantity based on CONCENTRATION!

Thank you for your reply~
I know PH means concentration. But how can I define the concentration for my specifed species? Can you get me some examples? Thank you. |
Re: How to define the PH value for my species ????
I hope I understand you properly. I just told you to convert pH into concentration by using its definition. pH=log_10(1/[H]) where [H] is concentration of H ions.
As far as concentration definition in Fluent is considered, you define it in terms of mass fraction. |
