Electrolysis - Wikipedia
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 …

2025年1月11日 · Electrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). Learn more about electrolysis in this article.
Hydrogen Production: Electrolysis | Department of Energy
Electrolysis is a promising option for carbon-free hydrogen production from renewable and nuclear resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen.
19.9: Electrolysis - Chemistry LibreTexts
Electrolysis can also be used to drive the thermodynamically nonspontaneous decomposition of water into its constituent elements: H 2 and O 2.However, because pure water is a very poor electrical conductor, a small amount of an ionic solute (such as H 2 SO 4 or Na 2 SO 4) must first be added to increase its electrical conductivity.
Electrolysis of water - Wikipedia
Device invented by Johann Wilhelm Ritter to develop the electrolysis of water. In 1789, Jan Rudolph Deiman and Adriaan Paets van Troostwijk used an electrostatic machine to make electricity that was discharged on gold electrodes in a Leyden jar. [3]
Faraday's laws of electrolysis - Wikipedia
Faraday discovered that when the same amount of electric current is passed through different electrolytes connected in series, the masses of the substances deposited or liberated at the electrodes are directly proportional to their respective chemical equivalent/equivalent weight (E). [3]
