WebDefinition: Redox Titration is a laboratory technique for determining the concentration of a given analyte by initiating a redox reaction between the titrant and the analyte. These titrations may necessitate the use of a potentiometer or a redox indicator. The titrant and analyte undergo an oxidation-reduction reaction, which is the basis for redox titration. WebThe purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations.
