Page 8 - The extension which the present investigations have enabled me to make of the facts and views constituting the theory of electro-chemical decomposition, will, with some other points of electrical doctrine, be almost immediately submitted to the Royal Society in another series of these Researches.
Page 44 - I have such conviction that the power which governs electro-decomposition and ordinary chemical attractions is the same; and such confidence in the overruling influence of those natural laws which render the former definite, as to feel no hesitation in believing that the latter must submit to them also. Such being the case, I can have, no doubt that, assuming hydrogen as 1, and dismissing small fractions for the simplicity of expression, the equivalent number or atomic weight of oxygen is 8, of chlorine...
Page 16 - The tube is bent in the middle ; one end is closed ; in that end is fixed a wire and plate, a, proceeding so far downwards, that, when in the position figured, it shall be as near to the angle as possible, consistently with the collection, at the closed extremity of the tube, of all the gas evolved against it. The plane of this plate is also perpendicular (720.).
Page 12 - ... it, the latter must be in a constant direction, which, according to present usage of speech, would be from east to west, or, which will strengthen this help to the memory, that in which the sun appears to move. If in any case of electro-decomposition we consider the decomposing body as placed so that the current passing through it shall be in the same direction, and parallel to that supposed to exist in the earth, then the surfaces at which the electricity is passing into and out of the substance...
Page 38 - They are combining bodies ; are directly associated with the fundamental parts of the doctrine of chemical affinity ; and have each a definite proportion, in which they are always evolved during electrolytic action. I have proposed to call these bodies generally ions, or particularly...
Page 14 - ... that the chemical decomposing action of a current is constant for a constant quantity of electricity, notwithstanding the greatest variations in its sources, in its intensity, in the size of the electrodes used, in the nature of the conductors (or non-conductors) through which it is passed, or in other circumstances.
Page 20 - ... water. 723. The next point in regard to which the principle of constant electro-chemical action was tested, was variation of intensity. In the first place, the preceding experiments were repeated, using batteries of an equal number of plates, strongly and weakly charged ; but the results were alike. They were then repeated, using batteries sometimes containing forty, and at other times only five pairs of plates ; but the results were still the same. Variations therefore in the intensity, caused...
Page 51 - I think, therefore, it would be more philosophical, and more directly expressive of the facts, to speak of such a body in relation to the current passing through it, rather than to the poles, as they are usually called, in contact with it; and say that whilst under decomposition, oxygen, chlorine, iodine, acids, etc., are rendered at its negative extremity, and combustibles, metals, alkalies, bases, etc., at its positive extremity.
Page 15 - The tubes were about eight inches long, 0.7 of an inch in diameter, and graduated. The platina plates were about an inch long, as wide as the tubes would permit, and adjusted as near to the mouths of the tubes as was consistent with the safe collection of the gases evolved. In certain cases, where it was required to evolve the elements upon as small a surface as possible, the metallic extremity, instead of being a plate, consisted of the wire bent into the form of a ring (fig.
