| Title | Unpublished letter, 'On the reabsorption of the mixed gases in a voltameter' from M H [Moritz Hermann] Jacobi to Michael Faraday |
| Creator | Jacobi; Moritz Hermann [Boris Semyonovich] (1801-1874); Prussian and Russian engineer; physicist |
| Date | 19 January 1847 |
| Description | Jacobi reports that if the mixed gases developed from the decomposition of water by a voltaic current are allowed to remain in the voltameter in which they were collected, in contact with the fluid which produced them, they by degrees diminish in volume, and ultimately disappear by being absorbed by the fluid. He has not yet fully determined the precise conditions on which this phenomenon depends, but suggest that it is owing to a portion of the mixed gases, diffused throughout the whole liquid, coming into contact with the platinum plates, and being recombined on the surface of those plates; and this process being renewed with every fresh portion of the gases which takes the place of the former, the whole of the gases are thus reconverted into water.
