Decomposition of Water Apparatus
notes: label: Description
content: August Wilhelm von Hofmann (1818–1892) was a German chemist who, in 1866, devised an apparatus for electrolyzing water—that is, for using electricity to decompose water into oxygen and hydrogen. This device, sometimes termed a Hofmann voltameter, is of that sort. It came from the Smithsonian Instrument Room, and was probably purchased by Joseph Henry, the physicist who served as the founding Secretary of the Institution.
