Page 36 - I propose to distinguish such bodies by calling those onions^ 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.
Page 145 - ... of the solid, upon the temperature, upon the concentration of the particular ion in the solution and upon the other ions present, or adsorbed previously by the solid. When the ion content of a liquid is vanishingly small, we shall have but little ion adsorption...
Page 280 - Every change of one of the factors of an equilibrium occasions a rearrangement of the system in such a direction that the factor in question experiences a change in a sense which is contrasted with the original change...
Page 146 - Freshly precipitated alumina is reported to be electro-positive; my idea regarding this is not that alumina on dissolving sends out rapidly diffusing hydroxyl ions and becomes positive against the solution, but that it adsorbs aluminium or hydrogen ions more easily than hydroxyl ions.
Page 238 - ... overvoltage of a metal, zinc, for instance, would likewise be the excess of the back electromotive force of the system: Zinc — >• zinc solution during electrolysis over the electromotive force of the reaction Solid zinc — > dissolved zinc ion. The overvoltage therefore, represents the excess energy required to form a substance over that given by the resolution of the product formed to the original state. It is the amount of energy by which one measures the irreversibility of the process...
Page 157 - In recent years a great deal of attention has been devoted to the study of parameteric systems containing both a varying reactive parameter (eg , capacitance) and a varying resistance [1-7].
Page 14 - The first states that the quantities of substances set free at the electrodes are directly proportional to the quantity of electricity which passes through the; solution.
Page 316 - According to principles to be explained in a later chapter, the product of the concentrations of the ions divided by the concentration of the...
Page 171 - There are certain obvious difficulties in the way of accepting these numbers as representing a physical reality. The first of them is startlingly large ; that, however, may not be a true difficulty. The third is so small as to involve the rejection of the entire molecular theory of fluids.
Page 233 - A COUNTER ELECTROMOTIVE FORCE CAUSED EITHER BY EXHAUSTION OF THE SUBSTANCES USED IN THE ELECTROLYTIC REACTION FASTER THAN THEY CAN BE REPLACED, OR BY THE ACCUMULATION OF THE PRODUCTS OF THIS REACTION FASTER THAN THEY CAN BE REMOVED.
