Answer / balakrishnan

Actually Citric acid is having three COOH group, due to
this we should get three end point. This can be acheived by
using potentiometry titration(Measure the pH variation with
respect to Volume added). The pKa values are 3.15, 4.77 and
5.19. Each pKa contributes one end point.
