69ron Rising Star Thread Starter Thread Starter Feb 5, 2009 #3 For example what's the pH of a 1% solution of mescaline HCl in water?
benzyme Moderator Moderator Donator Senior member Chemical engineer Chemical engineer extraordinaire Moderator Lab expert Feb 5, 2009 #4 :? technically, it should be neutral (pH ~ 7)
69ron Rising Star Thread Starter Thread Starter Feb 5, 2009 #5 Are you basing that off the pKa of mescaline?
benzyme Moderator Moderator Donator Senior member Chemical engineer Chemical engineer extraordinaire Moderator Lab expert Feb 5, 2009 #6 no, basing it off of past extraction procedures...and measurements taken by a pH meter
69ron Rising Star Thread Starter Thread Starter Feb 5, 2009 #7 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?

benzyme Moderator Moderator Donator Senior member Chemical engineer Chemical engineer extraordinaire Moderator Lab expert Feb 5, 2009 #8 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
