Basics of Potentiometry:
In this unit, you have learnt about electrode potentials, principles of potentiometer and measurement of potential, different types of reference electrodes: such as Calomel Electrode, Hydrogen Electrode, Silver-Silver Chloride Electrode and different types of indicator electrodes. We have also learnt about the measurement of potential and location of end points from the graphs obtained from the experimental values of emf and volume of titrant.
Various types of tirations such as acid-base titrations, redox titrations, precipitation titrations, complexometric titration and differential titrations were also explained in detail.
