Editing Redox (section)

==Redox reactions in industry==
[[Cathodic protection]] is a technique used to control the corrosion of a metal surface by making it the [[cathode]] of an [[electrochemical cell]]. A simple method of protection connects protected metal to a more easily corroded "[[sacrificial anode]]" to act as the [[anode]]. The sacrificial metal, instead of the protected metal, then corrodes. 

Oxidation is used in a wide variety of industries, such as in the production of [[:Category:Cleaning products|cleaning products]] and oxidizing [[ammonia]] to produce [[nitric acid]].{{cn|date=February 2024}}

Redox reactions are the foundation of electrochemical cells, which can generate electrical energy or support [[electrosynthesis]]. Metal [[ore]]s often contain metals in oxidized states, such as oxides or sulfides, from which the pure metals are extracted by [[smelting]] at high temperatures in the presence of a reducing agent. The process of [[electroplating]] uses redox reactions to coat objects with a thin layer of a material, as in [[Chrome plating|chrome-plated]] [[automotive]] parts, [[Plating#Silver plating|silver plating]] [[cutlery]], [[galvanization]] and [[gold-plated]] [[jewelry]].{{cn|date=February 2024}}
