Cyclic Voltammetry of ferrocene-ferrocenium system.

Introduction:

Cyclic voltammetry is an electroanalytical technique. It is a valuable technique that provides vital information about the oxidation state of an element in a compound. Various inorganic compounds contain transition metal centers with different oxidation states. When conditions provide stable redox forms during the time required to obtain a voltammogram i.e. current- potential curve. CV is a simple and direct method for measuring a complex standard reduction potential (E°). CV helps to determine the stability of a compound under different experimental conditions. Ferrocene is a highly investigated organometallic molecule. Bis(cyclopentadienyl)iron(II) or ferrocene, Fe(C5H5)2 has a sandwich structure with the iron sandwiched between two cyclopentadienyl rings.

It can undergo one-electron oxidation to form ferrocenium cation Fe(C5H5)2+ reversibly. Organic and aqueous mediums can be used to study ferrocene electrochemical behaviors.
