The Kolbe electrolysis or Kolbe reaction is an organic reaction named after Hermann Kolbe. [1] The Kolbe reaction is formally a decarboxylative dimerisation of two carboxylic acids (or carboxylate ions).
A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
A well-known electrosynthesis is the Kolbe electrolysis, in which two carboxylic acids decarboxylate, and the remaining structures bond together:; A variation is called the non-Kolbe reaction when a heteroatom (nitrogen or oxygen) is present at the α-position.
In electrochemistry, Faraday efficiency (also called faradaic efficiency, faradaic yield, coulombic efficiency, or current efficiency) describes the efficiency with which charge is transferred in a system facilitating an electrochemical reaction.
A galvanic cell (voltaic cell), named after Luigi Galvani (Alessandro Volta), is an electrochemical cell that generates electrical energy from spontaneous redox reactions. [3]
Protons tunnel across a series of hydrogen bonds between hydronium ions and water molecules.. The Grotthuss mechanism (also known as proton jumping) is a model for the process by which an 'excess' proton or proton defect diffuses through the hydrogen bond network of water molecules or other hydrogen-bonded liquids through the formation and concomitant cleavage of covalent bonds involving ...
Electrochemical kinetics is the field of electrochemistry that studies the rate of electrochemical processes. This includes the study of how process conditions, such as concentration and electric potential, influence the rate of oxidation and reduction reactions that occur at the surface of an electrode, as well as an investigation into electrochemical reaction mechanisms.
