  2. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    An equilibrium electrochemical cell exists in the state between an electrolytic cell and a galvanic cell. The tendency of a spontaneous reaction to push a current through the external circuit is exactly balanced by a counter-electromotive force so that no current flows. If this counter-electromotive force is increased, the cell becomes an ...

  3. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. [5] A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.

    The quantity of the products is proportional to the current, and when two or more electrolytic cells are connected in series to the same power source, the products produced in the cells are proportional to their equivalent weight. These are known as Faraday's laws of electrolysis. Each electrode attracts ions that are of the opposite charge.

    Electroplating – a process where a thin layer of metal is deposited onto the surface of an object using an electric current; Electrochemical cells – generates electrical energy from chemical reactions; Electrotyping – a process used to create metal copies of designs by depositing metal onto a mold using electroplating

    Industrially this process takes place in a special cell named Downs cell. The cell is connected to an electrical power supply, allowing electrons to migrate from the power supply to the electrolytic cell. [28] Reactions that take place in a Downs cell are the following: [28] Anode (oxidation): 2 Cl − (l) → Cl 2 (g) + 2 e −

  7. Exchange current density - Wikipedia

    en.wikipedia.org/wiki/Exchange_current_density

    The Tafel equation describes the dependence of current for an electrolytic process to overpotential. The exchange current density is the current in the absence of net electrolysis and at zero overpotential. The exchange current can be thought of as a background current to which the net current observed at various overpotentials is normalized.

  8. Electrolyte - Wikipedia

    en.wikipedia.org/wiki/Electrolyte

    Electrolytic conductors are used in electronic devices where the chemical reaction at a metal-electrolyte interface yields useful effects. In batteries , two materials with different electron affinities are used as electrodes; electrons flow from one electrode to the other outside of the battery, while inside the battery the circuit is closed ...

  9. Ion transport number - Wikipedia

    en.wikipedia.org/wiki/Ion_transport_number

    In the Hittorf method, electrolysis is carried out in a cell with three compartments: anode, central, and cathode. Measurement of the concentration changes in the anode and cathode compartments determines the transport numbers. [6] The exact relationship depends on the nature of the reactions at the two electrodes.
