69ron Esteemed member Joined Jun 10, 2008 Messages 5,522 Merits 42 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?
