Quick Summary

Amperometric titration is a chemical analysis technique used to determine the concentration of a substance in a sample. It involves gradually adding a known solution (titrant) to the sample until a reaction is complete, indicated by a signal. In amperometry, this signal is measured as electric current while maintaining a constant potential between electrodes.12

The current's change is monitored as the titrant is added. This allows for the determination of the analyte's concentration or the precise location of the reaction's end point. This method is a type of electroanalysis, utilizing electrical measurements to understand chemical properties.2
