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 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 ...
[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 ...
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:
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).

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)
