WebSep 7, 2024 · The redox potential of the solution is : E(FeX3 + / FeX2 +) = E°(FeX3 + / FeX2 +) + 0.059log[FeX3 +] [FeX2 +] = 0.77 + 0.059log(10X − 4) = 0.53V Now this potential cannot be directly measured. The only thing that can be measured is the difference of potentiel between this electrode and a reference, which is here SCE, at - 0.24 V. WebAll acid-base titrations that are measured by a pH probe are potentiometric; thus, this method is not as unusual as it may seem. You will conduct an oxidation-reduction reaction in this experiment in order to determine the amount of iron (II) ions in a solid sample of ferrous ammonium sulfate hexahydrate, (NH 4) 2 Fe (SO 4) 2 •6H 2 O.

Weboxidizing determination are potassium iodide, titanium (III) ions, iron (II) ions and vanadium (II) ions. The method of redox titration using iodine solution as a pentiter is called iodometry (Merino et al. 2016). In the analaitic process, iodine is used as an oxidation reagent (iodimetry) and iodide ion is used as a reducing reagent (iodometry). WebDec 12, 2024 · At the beginning of the titration, there are still many iron(II) ions floating around ready to be oxidised by any incoming permanganate. Towards the end, iron(II) is getting more scarce. ... In redox titrations, we titrate a substance with a reducing nature against a substance with an oxidising nature. $\ce{KMnO_4}$ is an oxidant.
