J The gaseous mixture under investigation was found to contain 21.96 vols, of methyl and 51.31 vols, of carbonic acid ; or, in other words, for every volume of the former, there are z\ volumes of the latter, instead of 2 volumes, as indicated by the above equation. These observations appear sufficient to prove, that in the electrolysis of acetic acid, even when employed in the form of a concentrated solution of its potash salt, a simultaneous decomposition of water takes place, which may perhaps be partially or entirely avoided by modifying the electrical current. ON THE ELECTROLYSIS OF ACETIC ACID* HAVING twenty years ago resolved acetic acid into carbonic acid and methyl, by the electrolysis of the aqueous solution of its potassium salt, I further examined the behaviour of free acetic acid towards * [From The Journal of the Chemical Society of London, Vol. 21 (1868), pp. 195-196-]
