How does potentiometric titration work
WebJan 28, 2024 · For any titration the titrant and analyte must react both quickly and to completion. This allows us to relate the quantity of one unknown reactant to that which is known using stoichiometry. The chemical reaction that shows the molar relationship between the titratrant and analyte is the analytical reaction. WebPotentiometric titration measures the given analyte concentration. In potentiometric titrations, two electrodes are generally used, one is the reference electrode and the other …
