Question

What is about the chemical scheme??

What is the relation between the cyclic voltammogram and chemical scheme??

Answer 1

• A chemical scheme or reaction scheme is a visual aid to show how one compound can be converted into another. A reaction scheme is also known as a reaction pathway because it shows you the chemical path taken to convert one compound in another. A reaction scheme, or reaction pathway, is a flow chart of chemical reactions.
• Cyclic voltammetry (CV) is a type of potentiodynamic electrochemical measurement. In a cyclic voltammetry experiment, the working electrode potential is ramped linearly versus time. Unlike in linear sweep voltammetry, after the set potential is reached in a CV experiment, the working electrode's potential is ramped in the opposite direction to return to the initial potential. These cycles of ramps in potential may be repeated as many times as needed. The current at the working electrode is plotted versus the applied voltage (that is, the working electrode's potential) to give the cyclic voltammogram trace. Cyclic voltammetry is generally used to study the electrochemical properties of an analyte in solution or of a molecule that is adsorbed onto the electrode.
• Chemical scheme or reaction scheme comes in handy while doing cyclic voltammetry.
