Study Notes
Indicator Electrode
- The indicator electrode is an electrode whose potential changes in response to changes in the concentration of the analyte in the solution being measured.
- Also referred to as the working electrode.
- Example: upper electrode.
Potentiometry
- The principle of potentiometry is employed in measuring the pH of substances.
Test your knowledge on indicator electrodes and potentiometry principles used in measuring analyte concentrations and pH values. Learn about the working electrode and its role in detecting changes in solution compositions.
