Web7 apr. 2024 · That’s why potentiometric titration is preferred over manual titrations. 1st potentiometric titration was carried out by Robert Behrend in 1893. What is Potentiometric Titration? Potentiometric titration is a technique similar to direct titration, but in this, no indicator reagent is used; instead, an electrode is used as an indicator. WebThe easiest way to do this is to multiply the volume in mL × 10 -3 . Calculate the moles of reactant (titrant) (n) for which you have both volume (V) and concentration (c): n = c x V From the redox reaction equation find the mole ratio (stoichiometric ratio): known reactant (titrant) : unkown reactant (analyte)
