Determination of copper sulphate by iodometry
WebThe determination of copper compounds (copper sulphate) depends on the instability of cupric iodide formed by the reaction between the copper sulphate and potassium iodide … 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).
