Does anyone know the pH of mescaline hydrochloride?
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.

What exactly do you mean? pH is dependent on concentration of protons in a solution.

For example what's the pH of a 1% solution of mescaline HCl in water?

Confused

technically, it should be neutral (pH ~ 7)

Are you basing that off the pKa of mescaline?

no, basing it off of past extraction procedures...and measurements taken by a pH meter

Well the pKa of mescaline is 9.56, so at pH 7.56 99% is ionized. At pH 7 about 99.5% is ionized.

If an acid like citric acid were used instead of HCl, that would change the pH of the solution or would you still get about pH 7?

yeah, you should still get a pH ~ 7.
the citrate salt is even more hygroscopic than the HCl salt, so of course it tends to be resinous
