Redox titration

In redox reactions the total number of electrons donated must equal the total number of electrons gained. In today’s experiment the mass/volume percent of the active ingredient in bleach, sodium hypochlorite (NaOCl), is determined by redox titration. The method used is iodine-thiosulfate titration.

A redox titration is a titration in which the analyte and titrant react through an oxidation-reduction reaction. As in acid-base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution. A redox titration example: titrating an Fe(II) solution with potassium permanganate. Experiment 26 in CHEM 1212K is titled "Redox Titration of a Metal Oxalate Compound with Permanganate."In complexometric and redox reactions, the success of the titration depends to a large extent on the working conditions being respected THROUGHOUT THE TITRATION. In the event of poor results check the pH – in particular at the BEGINNING and at the END of the analysis. As a general rule, inflection-point titration is ideal for these eacr oni . t s
