Hoffman Voltameter is a specialized laboratory apparatus used to demonstrate and measure the electrolysis of water into hydrogen and oxygen gases. It consists of a central reservoir connected to two vertical graduated gas-collection tubes (electrodes) and is typically made from borosilicate glass for chemical resistance and clarity. Platinum or carbon electrodes are used at the base of each tube to conduct electric current. This apparatus is widely used in chemistry and physics education to visually demonstrate the principles of electrolysis, electrochemical reactions, gas laws, and stoichiometry.
