Paper, 'Influence of the chemical energy of electrolytes upon the "minimum point" and change of potential of a voltaic couple in water' by George Gore

Description

Gore writes: 'In a communication to the Royal Society, May 3rd, 1888, on "The Effect of Chlorine upon the Electro-motive Force of a Voltaic Couple" [PP/12/7], and in a subsequent one on "The Minimum Point of Change of Potential of a Voltaic Couple" [see PP/12/20], I have shown that by opposing to each other two currents of equal electromotive force from two perfectly similar couples of magnesium-platinum or zinc-platinum in distilled water, and gradually adding to one of the cells sufficiently minute quantities of a suitable substance, sue as chlorine, hydrochloric acid, or a soluble salt, &c., the voltaic balance is not disturbed until a certain definite proportion of the substance has been added, and that the proportion required to be added is excessively small (about 1 in 17,000 millions) in the case of chlorine with. a magnesium-platinum couple, and extremely different with unlike substances.'
