Answer Posted / 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.

why are measure gas flow " ml " in Gas chromatography
In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.
