He wrote many papers on geometrical optics and on molecular physics, but his great claim to remembrance is that he first suggested, "on the basis of Faraday's law of Electrolysis, that an absolute unit of quantity of electricity exists in that amount of it which attends each chemical bond or valency and gave the name, now generally adopted, of electron to this small quantity."
It tarnishes more easily and inflames less easily than cerium. Didymium resembles lauthanum. The metals were all obtained by electrolysis of the chlorides.
It was he who gave the name electrolysis to decomposition by the electric current; he also proposed to call the wires, or conductors connected with the battery, or other electric source, the electrodes, naming that one which was connected with the positive terminal, the anode, and that one connected with the negative terminal, the cathode.
"As the gas is generated at the anode, a commotion is created in the liquid, which brings a fresh and saturated solution of electrolyte between the electrodes for electrolysis, and makes it continuous in its action.
Tin may be easily estimated by electrolysis; it can be separated from its hydrochloric acid solution, or from its double salt with ammonium oxalate, as a beautiful silver gray coating on the platinum. When the ammonium oxalate is substituted by the potassium salt, the operation becomes more difficult, as a basic salt is formed at the opposite pole, and is not easily reduced.
The water inside the tank seemed the same as before, only on each electrode there appeared bubbles, on one bubbles of oxygen, on the other of hydrogen. The water was decomposing under the current by electrolysis. Another moment he surveyed his work to see that he had left no loose ends. Then he picked up his bag and moved toward the cellar steps.
The refining of copper and the separation of copper, gold, and silver by electrolysis have thus far attracted the greatest amount of attention, but a commercial success has also been achieved in the dry reduction by electricity of some of the more valuable metals by the Cowles Electric Smelting and Aluminum Company, of Cleveland, Ohio.
But roasting water out of lunar gypsum rock is an easy trick. And oxygen can be derived from water by simple electrolysis." "Hell, we know all that, Harv," Ramos laughed. So Harv Diamond gave them the lowdown on the shortage of girls yet in Serenitatis Base, on the Moon. Just the same, it was growing like corn in July, and was already a pretty good leave-spot, if you liked to look around.
In practice, the desired result is obtained by starting with small volumes of solution, using as large an electrode surface as possible, and by stirring the solution to bring the ions in contact with the electrodes. This is, in general, a more convenient procedure than that of increasing the potential of the current during electrolysis, although that method is also used.
The canyon dry at one place near the lower edge of the city, the water all electrified, resolved into piped hydrogen and oxygen. Like a tremendous clock ticking, the water, momentarily dammed back, was released in a torrent to the electrolysis vats. The hissing gases, under tremendous pressure, raised up the heavy-weighted tops of two expanding tanks.
