1. Recreate the graph in the potentiometric titration of a diprotic acid (FW=116.07) given the following data. Show necessary computations.
Mass of acid = 0.1032 g
Ka1 = 3.21 × 10-5
Ka2 = 8.85 × 10-8
pH at EP1 = 5.77
pH at EP2 = 7.69
NNaOH = 0.05 N
Note: Label EP1 and EP2. The graph should show the actual volume of titrant (mL) and pH level at ½ EP1, EP1, ½ EP2, and EP2.
