Epenguin, you are right when I checked the pH of 0.1 M Citric acid its value was exactly equal the value I got using the monotropic formula when using tlhe first pKa1of Citric acid. This means at higher concentration of a weak acid I can predict it's pH using the formula. Thanks again for your...

Thanks for your input :)

Thank you Borek for your valuable explanation.

I got granulated citric acid 99.9% pure Food Grade, my question is which pKa to use in the pH formula since this acid has three pKa values? I am trying to calculate a pH of a certain molar concentration. I appreciate your input. The formula I am using is pH=1/2(pKa-log molar concentration of...
