If I were to add a small amount of triethylamine into water, I understand that it will exist almost exclusively in its protonated form (as the pKa of protonated triethylamine is ~10-11, and so at pH=7.0 it will be protonated). I'm interested in understanding what would happen if I were to add an equivalent ...
