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 42 - I may be allowed to express a hope, that the endeavour will always be to make it a table of real, and not hypothetical, electro-chemical equivalents ; for we shall else overrun the facts, and lose all sight and consciousness of the knowledge lying directly in our path.
Page 38 - Then, again, the substances into which these divide, under the influence of the electric current, form an exceedingly important general class. 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.
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 37 - I at first laid down, namely, that the chemical power of a current of electricity is in direct proportion to the absolute quantity of electricity which passes (377, 783).
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 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...
