The definition of the voltammograms is to be stated.
Cyclic voltammetry is a form of potentiodynamic electrochemical measurement. In this type of measurement, the potential of the working electrode is plotted linearly with time. This measurement is generally used for studying the electrochemical properties of the desired analyte in the solution.
The definition of hydrodynamic voltammetry is to be stated.
The hydrodynamic voltammetry technique is different from other voltammetry techniques which are unstirred experiments. The solution in the hydrodynamic voltammetry is kept stirring vigorously. The stirring can be provided by means of rotation of the electrode at a constant speed.
The definition of Nernst diffusion layer is to be stated.
The diffusion layer is a region adjacent to the electrode, where the concentrations are different from that in the solution.
At slower rates of scan, the diffusion layer is large whereas at faster rates of the scan, the diffusion layer is comparatively small.
The definition of mercury film electrode is to be stated.
Voltammetry involves plotting the current against the applied potential. This type of measurement is usually used to study the electrochemical properties of the analytes in the solutions or the molecules that have been adsorbed on the electrode. There are a variety of voltammetry methods available. These include linear sweep voltammetry, staircase voltammetry, alternating current voltammetry etc.
The definition of half wave potential is to be stated.
For any given electrolyte, half wave potential is unique for each of the elements and for it’s different valence states and forms. Observation of the peak current at any specific half wave potential helps in identification of the chemical species that produces the current.
The definition of voltammetric sensor is to be stated.
Voltammetric sensor is a device that is used for the purpose of carrying out voltammetry measurements.
It acts as an electrode in this process and helps determine the electrochemical properties of the analyte in the solution.
