The Extraction of Copper - Chemistry LibreTexts
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 … See more The word "electrolysis" was introduced by Michael Faraday in 1834, using the Greek words ἤλεκτρον [ɛ̌ːlektron] "amber", which since the 17th century was associated with electrical phenomena, and λύσις [lýsis] meaning … See more Electrolysis is the passing of a direct electric current through an electrolyte producing chemical reactions at the electrodes and decomposition of the materials. The main components required to achieve electrolysis are an See more Using a cell containing inert platinum electrodes, electrolysis of aqueous solutions of some salts leads to the reduction of the … See more • Alkaline water electrolysis • Castner–Kellner process • Electrolytic cell • Electrochemical engineering • Faraday's law of electrolysis See more In the early nineteenth century, William Nicholson and Anthony Carlisle sought to further Volta's experiments.
