  2. 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.

  3. Earth battery - Wikipedia

    en.wikipedia.org/wiki/Earth_battery

    The simplest earth batteries consist of conductive plates from different metals of the electropotential series, buried in the ground so that the soil acts as the electrolyte in a voltaic cell. As such, the device acts as a primary cell. When operated only as electrolytic devices, the devices were not continuously reliable, owing to drought ...

    Cell diagram. Pt(s) | H 2 (1 atm) | H + (1 M) || Cu 2+ (1 M) | Cu(s) E° cell = E° red (cathode) – E° red (anode) At standard temperature, pressure and concentration conditions, the cell's emf (measured by a multimeter) is 0.34 V. By definition, the electrode potential for the SHE is zero. Thus, the Cu is the cathode and the SHE is the ...

  5. Salt bridge - Wikipedia

    en.wikipedia.org/wiki/Salt_bridge

    [1] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. [1] [2] In short, it functions as a link connecting the anode and cathode half-cells within an electrochemical cell. [3] It also maintains electrical ...

  6. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    A galvanic cell consists of two half-cells, such that the electrode of one half-cell is composed of metal A, and the electrode of the other half-cell is composed of metal B; the redox reactions for the two separate half-cells are thus: A n + + n e − ⇌ A B m + + m e − ⇌ B. The overall balanced reaction is:

  7. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    The voltage delivered to a load decreases as the current drawn increases and as the cell discharges. A cell is considered fully discharged when the voltage drops to about 0.9 V. [13] Cells connected in series produce a voltage equal to the sum of the voltages of each cell (e.g., three cells generate about 4.5 V when new).

  9. Talk:Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Talk:Galvanic_cell

    An electrochemical cell can mean a galvanic cell, or be a general term for galvanic and electrolytic cells. Basically, a galvanic cell generates an electromotive force through a spontaneous redox reaction, where electrolysis requires an external current before the reaction will occur. splintax (talk) 07:27, 23 May 2006 (UTC)
