Does the presence of acetic acid affect the solubility of anthranilic acid in water?
It sure seems like it from the reading I've done, and I believe I just witnessed some precipitation that wouldn't have happened without some added
acetic acid, but it's hard to be sure. I know it has some screwy solubility properties, but I've never actually read anything that says AcOH affects
the precipitation PH range.

It's a weak acid with the pKa well situated to hit the isoelectric point of anthranilic acid.
