Hofmann voltameter

The Hofmann voltameter is often used as a small-scale electrolytic cell.

This kind of voltameter is sometimes called Hofmann voltameter.

August von Hofmann proposes the now standard system of hydrocarbon nomenclature and invents the Hofmann voltameter.

(A Hofmann voltameter cannot be used to weigh electric current in this fashion, as the platinum electrodes are too inert for plating.)

The Hofmann voltameter is an apparatus for electrolyzing water, invented by August Wilhelm von Hofmann.

When current is run through the Hofmann voltameter, gaseous oxygen forms at the anode (positive) and gaseous hydrogen at the cathode(negative).

A Hofmann voltameter is often used as a demonstration of stoichiometric principles, as the two-to-one ratio of the volumes of hydrogen and oxygen gas produced by the apparatus illustrates the chemical formula of water, HO.
