Consider The Hofmann Voltameter: In this process, electrical energy is put in to drive to reaction in the non - spontaneous direction: sf(2H_2Orarr2H_2+O_2) On this basis you would expect a voltage of at least 1.23 V would need to be applied to drive the reaction. WebVoltameter definition, a device for measuring the quantity of electricity passing through a conductor by the amount of electrolytic decomposition it produces, or for measuring the strength of a current by the amount of such decomposition in a given time.

WebThe chemical bonds in the water molecules are broken apart and rearranged, resulting in two gaseous products. These gases are hydrogen and oxygen. Therefore, the products produced during the electrolysis of acidified water using a Hoffman voltameter are … WebHydrogen is released at the cathode and collected in a graduated tube so that its volume can be measured. The volume is adjusted to standard temperature and pressure and the mass of hydrogen is calculated from the volume. This kind of voltameter is sometimes called Hofmann voltameter . Historical derivation of the name [ edit]
