Understand the Electrolysis of Water. Click on the link to Watch the VIDEO explanation:
Watch Video
The electrolytic cell used for electrolysis of water is called Hoffman's Voltmeter. Acidulated water is the electrolyte taken in the limbs of the voltameter. The electrodes are made of Platinum. Anode is connected to the positive terminal of the battery and cathode to negative terminal. On the passage of current water dissociates into hydrogen ions and hydroxyl ions. At cathode discharged hydrogen atoms from hydrogen molecules. At anode hydroxyl ions are discharged that forms water and oxygen gas. Oxygen and Hydrogen are collected in the limbs of voltameter. The amount of hydrogen collected is double the amount of oxygen. here are the reactions that takes place.
