Calculate the ratio of acidic and basic forms and express them as [A]/[HA] ratio or [B]/[BH] of the titrating group at the following pH values: α-carboxyl @ 1.4, 1.9, 2.4, 2.9, 3.4; α-amino @ 8.1, 8.6, 9.1, 9.6, 10.1. Plot pH vs. [B]/[BH] for each group, on the same graph. Compare similarities or disparities in the titration of each group.
