  2. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. [ 1 ] : 64, 89 [ 2 ] : GL7 The external energy source is a voltage applied between the cell's two electrodes ; an anode (positively charged electrode) and a cathode (negatively ...

  3. Electrolytic process - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_process

    An electrolytic process is the use of electrolysis industrially to refine metals or compounds at a high purity and low cost. Some examples are the Hall-Héroult process [1] used for aluminium, or the production of hydrogen from water. Electrolysis is usually done in bulk using hundreds of sheets of metal connected to an electric power source.

  4. Castner–Kellner process - Wikipedia

    en.wikipedia.org/wiki/Castner–Kellner_process

    Castner–Kellner process. The Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution (usually sodium chloride solution) to produce the corresponding alkali hydroxide, [1] invented by American Hamilton Castner and Austrian Carl Kellner in the 1890s. [2][3] It is a type of chloralkali process, but in this ...

  5. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Electrolysis of water is using electricity to split water into oxygen (O. 2) and hydrogen (H. 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or 'gas bottles', hydrogen can be ...

    The video describes the electrolytic process as it is occurring on Captain Kidd's cannon, which is on display and currently undergoing the electrolytic process. Other languages English: A video describing the process of electrolytic reduction used in a display at The Children's Museum of Indianapolis within the Treasures of the Earth exhibit.

  7. Electrolysis - Wikipedia

    en.wikipedia.org/wiki/Electrolysis

    e. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.

  8. 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.

  9. Proton exchange membrane electrolysis - Wikipedia

    en.wikipedia.org/wiki/Proton_exchange_membrane...

    Proton exchange membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE) [3] that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electrolyzer was introduced to overcome the issues of partial load, low ...
