Voltmeter Hoffman

Details:

Product Type: Hofmann Voltameter / Electrolysis Apparatus

Material: High-Quality Borosilicate Glass with Graduated Cylinders

Components: Dual graduated collection tubes with stopcock taps, central reservoir bulb tube, and removable electrodes

Application: Demonstrating the electrolysis of water and determining the volumetric composition of hydrogen and oxygen gases

• The Hofmann Voltameter is an apparatus used to demonstrate the process of breaking down of water using electrolysis.
• This device comprises of two vertically placed cylindrical columns made of tough borosilicate glass and fitted with taps that open upwards to allow the collection of the gases that are formed during the reaction. In addition to this, there exists a central column with a funnel-shaped bulb.
• There exist removable electrodes placed on the bottom of the columns and through which electric current flows through acidic water to cause the evolution of hydrogen and oxygen gases. The proportions at which the gases are evolved are in a ratio of 2:1.
• The clearly printed graduated scales on each column allow students to measure and compare the gas volumes accurately, making it an essential instrument for chemistry and physics laboratories.
