A 100 mL solution of 0.1 M amino acid (AA) at pH 1.0 was titrated with 1.0 M NaOH solution. The pH was monitored, and the results were plotted on a graph, as shown below. The key points in the titration are designated I to VII. 12 VII 10 -9.7 VI 17 V pH 6 3.9 4 12.0 IV II 1. 0.5 1.5 2.5 3 Equivalents of OH
