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 as ores using an electrolytic cell.The voltage that is needed for electrolysis to occur is called the decomposition potential.

Electrolytic Cells - Chemistry LibreTexts

Electrolytic cells, like galvanic cells, are composed of two half-cells--one is a reduction half-cell, the other is an oxidation half-cell. The direction of electron flow in electrolytic cells, however, may be reversed from the direction of spontaneous electron flow in galvanic cells, but the definition of both cathode and anode remain the same, where reduction takes place at the cathode and ...

copper metal produced at the cathode was not coated on the mesh, instead it settled at the bottom of the solution as small particles. I thought this might be because of some impurity outside of the mesh so I let it wait in 1M hydrochloric acid solution for a minute. Then I ran the experiment again and this time the copper was plated on the

copper extraction and purification - chemguide

Electrolytic refining The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplifiedview of a cell. At the cathode, copper(II) ions are deposited as copper.

ELECTROLYTIC RUST REMOVAL (ELECTROLYSIS)

Please note that electrolytic cleaning doesn't work for non-ferrous metals such as copper, bronze, brass, pewter, tin or aluminium. The corrosion products found on these metals are rarely formed by electrolytic action and therefore the process cannot be reversed electrolytically. In the case of copper and tin alloys the treatment would be harmless, although I understand that aluminium could be ...
