Predicting charge of organic compound at certain pH

  1. Mar 19, 2017 #1
    Which property of compounds, organic ones in particular, can help us predict their charge(s) at a specific pH? Is pKa/pKb the only one? I would like some confirmation on this. Thank you very much!

    pKa and pKb help predict charges related to the acid/base (mostly protonoation) reactions. As these dominate, pKa/pKb is usually enough.

    Actually I can't think of a counterexample ATM. Which probably means I will feel ashamed later today.

    This information is enough. Thank you very much!
