Explain in brief the three industrial applications of electrolysis? |
|
Answer» Electroplatingis used to coat one metal with another metal by using electrolysis. Electroplating is usually done to improve the appearance of the metal or prevent the corrosion of the metal.Chromium plating is used to prevent iron from rusting. Extraction Of Reactive Metals Reactive metals are the metals that occupy the top positions in the electrochemical series. Metals that are higher than zinc in the electrochemical series are extracted using electrolysis. These very reactive metals cannot be extracted by other metals such as reduction with carbon. The reactive metals are obtained by electrolyzing a molten ionic compound of metal. Production of Chemicals: Many chemicals such as caustic soda (NaOH) chlorine gas etc. are manufactured by electrolysis on large scale. Potassium permaganate hydrogen and oxygen etc. are also produced by electrolysis on a large scale. |
