One electrochemical technique involves first depositing an analyte on the surface of an electrode, then using an applied current to remove the analyte via a reduction or oxidation reaction. What is this method called?

MCQs on the analytical theories and methods of qualitative and quantitative chemical analysis. Topics include gravimetric analysis, titrations, ultraviolet-visible (UV-Vis), infrared (IR), and nuclear magnetic resonance (NMR) spectroscopies, atomic absorption and emission, fluorescence and phosphorescence, chromatographic methods, including, column chromatography, gas chromatography (GC), and high pressure liquid chromatography (HPLC), electrophoresis, and electrochemical analysis techniques.
