  2. Electrochemical potential - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_potential

    In electrochemistry, the electrochemical potential of electrons (or any other species) is the total potential, including both the (internal, nonelectrical) chemical potential and the electric potential, and is by definition constant across a device in equilibrium, whereas the chemical potential of electrons is equal to the electrochemical ...

  3. Fermi energy - Wikipedia

    en.wikipedia.org/wiki/Fermi_energy

    In a Fermi gas, the lowest occupied state is taken to have zero kinetic energy, whereas in a metal, the lowest occupied state is typically taken to mean the bottom of the conduction band. The term "Fermi energy" is often used to refer to a different yet closely related concept, the Fermi level (also called electrochemical potential).

  4. Electrochemistry - Wikipedia

    en.wikipedia.org/wiki/Electrochemistry

    The electrochemical cell voltage is also referred to as electromotive force or emf. A cell diagram can be used to trace the path of the electrons in the electrochemical cell. For example, here is a cell diagram of a Daniell cell: Zn(s) | Zn 2+ (1 M) || Cu 2+ (1 M) | Cu(s) First, the reduced form of the metal to be oxidized at the anode (Zn) is ...

  5. Electroanalytical methods - Wikipedia

    en.wikipedia.org/wiki/Electroanalytical_methods

    Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition. Therefore, the difference in ...

  6. Chemical potential - Wikipedia

    en.wikipedia.org/wiki/Chemical_potential

    For example, n-type silicon has a higher internal chemical potential of electrons than p-type silicon. In a p–n junction diode at equilibrium the chemical potential (internal chemical potential) varies from the p-type to the n-type side, while the total chemical potential (electrochemical potential, or, Fermi level) is constant throughout the ...

  7. Electrochemical window - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_window

    The electrochemical window (EW) of a substance is the electrode electric potential range between which the substance is neither oxidized nor reduced. The EW is one of the most important characteristics to be identified for solvents and electrolytes used in electrochemical applications. The EW is a term that is commonly used to indicate the ...

  8. Electrochemical kinetics - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_kinetics

    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.

  9. Reference electrode - Wikipedia

    en.wikipedia.org/wiki/Reference_electrode

    The simplest is when the reference electrode is used as a half-cell to build an electrochemical cell. This allows the potential of the other half cell to be determined. An accurate and practical method to measure an electrode's potential in isolation (absolute electrode potential) has yet to be developed.
