Excerpt from Journal of the Chemical Society, 1903, Vol. 84: Abstracts of Papers on Physical, Inorganic, Mineralogical, Physiological, Agricultural, and Analytical Chemistry; Part II Limit of the Intensity of a Current from a Voltaic Element capable of producing Appreciable Electrolysis in a Voltameter. Marcelin P. E. Berthelot (compt. Rend., 1902, 135, 485 - 492. Compare Abstr., 1902, ii, 546, 547, - In a voltameter containing only dilute sulphuric acid, the external pressure exerts such an influence that as it diminishes a greater resistance may be introduced into the circuit, and there will still be appreciable electrolysis. The con centration of the acid scarcely modifies the intensity of the current required to produce appreciable electrolysis, but in this respect the influence of temperature is very great. With pyrogallol in the voltameter, the effect of the external pressure is the same as without it, and the concentration of the acid has no influence, but when a large excess of pyrogallol is used the cohesion of the liquid is so modified that the bubbles of hydrogen are evolved less freely.
