A potentiometric titration belongs to chemical methods of analysis in which the endpoint of the titration is monitored with an indicator electrode that records the change of the potential as a function of the amount (usually the volume) of the added titrant of exactly known concentration. Use the mixture titration data to find the pH at each equivalence point. POTENTIOMETRIC TITRATION It’s a volumetric method in which potential between two electrodes (reference & indicator) is measured as a function of added reagent volume. By suitable modification in the data analysis Gran plot methodology may be extended as suggested by Schwartz. Potentiometric Redox Titration e.g., Titrate 100.0 mL of 0.0500 M Fe2+ with 0.100 M Ce4+.The equivalence point occurs when Ve = 50.0 mL. Gran II linearization method is one of the most cited scientific papers (over 2500 cites) and has been applied in a variety of fields.
