9.4: Redox Titrations - Chemistry LibreTexts

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.
