It has been such a long time, that I totally forgot how it works.
I am interested in the charge of jasmonic acid at different concentrations. More specifically, I want to know at what pH my molecule has no charge (or I should rather say jasmonic acid would occur as a zwitter ion).
Only the decaboxylic group can be deprotonated at higher pH.
Is it correct to assume that most of the time, when you have an acidic compound it would predominantly occur in a nonionic form?
Does the $\log{D}$ say anything about this? does the maximum $\log{D}$ value corresponds to the pH at the iso electric point?
If we would take aspirin for example

at what pH should I expect the uncharged version?
