A time-dependent potential is applied to a working electrode.
is the study of how electric current responds to changes in applied potential, acting as a "molecular interrogation" to identify and quantify chemical species. By measuring the flow of electrons during oxidation and reduction (redox) reactions, scientists can determine the concentration, stability, and reactivity of an analyte. understanding voltammetry pdf download
When the potential reaching the electrode provides enough energy to cause a redox reaction, a current is produced. A time-dependent potential is applied to a working electrode
The resulting data is plotted as a voltammogram, which serves as a "chemical fingerprint". The peak current is directly proportional to the concentration of the species in the solution. 2. The Electrochemical Cell Setup scientists can determine the concentration
