For example: p-benzoquinone can be reduced to hydroquinone at the cathode: + 2 e − + 2 H + → . In the last example, H + ions (hydrogen ions) also take part in the reaction and are provided by the acid in the solution, or by the solvent itself (water, methanol, etc.). Electrolysis reactions involving H + ions are
Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminum and other chemicals. Electroplating (e.g., of copper, silver, nickel, or chromium) is done using an electrolytic cell. Electrolysis is a technique that uses a direct electric current (DC).
Electrolysis of water is using electricity to split water into oxygen (O 2) and hydrogen (H ... This is a prime example of a competing for side reaction.

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 .
The electrolysis of water into gaseous oxygen and hydrogen is a typical example. The relation between the equilibrium constant, K, and the Gibbs free energy for an electrochemical cell is expressed as follows: = =.
Anion exchange membrane (AEM) electrolysis is the electrolysis of water that utilises a semipermeable membrane that conducts hydroxide ions (OH −) called an anion exchange membrane. Like a proton-exchange membrane (PEM), the membrane separates the products, provides electrical insulation between electrodes, and conducts ions.
An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.
