Cycling voltametry of lead electrode
The experimental setup for cyclic voltammetry consists of an electrochemical cellcontaining five major components. 1. The working electrode, where the compound of interest is reduced (Cn+ → C(n−1)+ ) or oxidised (Cn+ → C(n+1)+). 2. The counter electrode, which completes the circuit with the … See more Cyclic voltammetry is a sophisticated potentiometric and voltammetric method. During a scan, the chemical either loses an electron (oxidation) or gains an electron (reduction). This will … See more A cyclic voltammogram is the ‘duck-shaped’ plot generated by cyclic voltammetry. In the example cyclic voltammogram above, the scan starts at -0.4V and sweeps … See more Broadly speaking, voltammetric techniques can be categorised as being either sweep type or polarography-like.
