Electrochemical engineering is applied in industrial water electrolysis, electrolysis, electrosynthesis, electroplating, fuel cells, flow batteries, decontamination of industrial effluents, electrorefining, electrowinning, etc. The primary example of an electrolysis-based process is the Chloralkali process for caustic soda and chlorine production. Other inorganic chemicals produced by electrolysis include:
* Ammonium persulfate
* Chlorine
* Electrowinning
* Fluorine
* Hydrogen peroxide
* Manganese dioxide
* Ozone
* Potassium dichromate
* Potassium permanganate
* Sodium chlorate
* Sodium hypochlorite
* Sodium persulfate
* Silver nitrate
* White lead (Basic lead carbonate)
