If you were to titrate a 0.1 M solution Histidine (HA) with your standardized HCl solution and follow it with a pH meter, the titration curve would reveal a starting pH at 7.8 and one equivalence point at about a pH of 3.8. This equivalence point would correspond corresponds to the point where all of the HA has...
