Seite 253 - All the facts show us that that power commonly called chemical affinity, can be communicated to a distance through the metals and certain forms of carbon; that the electric current is only another form of the forces of chemical affinity ; that its power is in proportion to the chemical affinities producing it ; that when it is deficient in force it may be helped by calling in chemical aid, the want in the former being made up by an equivalent of the latter; that, in other words, the forces termed,...
Seite 47 - I have rather," he writes in 1831, "been desirous of discovering new facts and new relations dependent on magnetoelectric induction, than of exalting the force of those already obtained, being assured that the latter would find their full development hereafter.
Seite 178 - I propose to distinguish such bodies by calling those anions which go to the anode of the decomposing body; and those passing to the cathode, cations; and when I have occasion to speak of these together, I shall call them ions. Thus, the chloride of lead is an electrolyte and when electrolysed evolves the two ions, chlorine and lead, the former being an onion, and the latter a cation.
Seite 236 - Or, if we adopt the atomic theory or phraseology, then the atoms of bodies which are equivalents to each other in their ordinary chemical action, have equal quantities of electricity naturally associated with them. But I must confess I am jealous of the term atom; for though it is very easy to talk of atoms, it is very difficult to form a clear idea of their nature, especially when compound bodies are under consideration.
Seite 176 - In place of the term pole, I propose using that of Electrode*, and I mean thereby that substance, or rather surface, whether of air, water, metal, or any other body, which bounds the extent of the decomposing matter in the direction of the electric current.
Seite 271 - ... and advanced the hypothesis, " that chemical and electrical attraction were produced by the same cause, acting in one case on particles, in the other on masses ;" and that the same property, under different modifications, was the cause of all the phenomena exhibited by different voltaic combinations.
Seite 211 - 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.
Seite 102 - The general conclusion which must, I think, be drawn • Edinburgh Phil. Journal, ii. p. 249. Identity of electricities. [SERIES III. from this collection of facts is, that electricity, whatever may be its source, is identical in its nature.
Seite 236 - ... the results prove that the quantity of electricity which, being naturally associated with the particles of matter, gives them their combining power is able, when thrown into a current, to separate those particles from their state of combination; or, in other words, that the electricity which decomposes and that which is evolved by the decomposition of a certain quantity of matter are ali\e.
Seite 177 - Researches, also, to class bodies together according to certain relations derived from their electrical actions (822.) ; and wishing to express those relations without at the same time involving the expression of any hypothetical views, I intend using the following names and terms. Many bodies are decomposed directly by the electric current, their elements being set free ; these I propose to call electrolytes :J Water, therefore, is an electrolyte.
