Understand the preparation of hydrogen by electrolysis of water. click on the link to Watch the VIDEO explanation: Watch Video
The electrolytic cell used for electrolysis of acidulated water is called Hoffman's voltameter. On the passage of electric current water dissociates into hydrogen ions and hydroxyl ions. At the cathode hydrogen ions are discharged as hydrogen atoms that forms hydrogen molecules. At the anode hydroxyl ions are discharged as water and oxygen gas. Here are the reactions taking place during the process of electrolyses.
