Electrochemical analysis
It is a qualitative and quantitative methods of analysis based on electrochemical phenomena occurring within a medium or at the phase boundary and related to changes in the structure, chemical composition, or concentration of the compound being analyzed. Electroanalytical methods containing the analyte measures the potential (volts) and/or current(amps) in an electrochemical cell . These methods can be categorized according to which aspects of the cell are controlled and measured. The four main categories are potentiometry which is used to measure the difference in electrode potentials, coulometry which is used to measure the transferred charge that is measured over time, amperometry is used to analyze the cell's current that is measured over time, and voltametry is used so as the cell's current is measured while actively altering the cell's potential. All the potentials and ampheres related to current can be estimated under the class of this electrochemical analysis.
