This second part will be especially experimental. My observations of the dissociation of matter led me into very varied researches. Notwithstanding their fragmentary nature, they may, I think,interest the reader; and the account of them will be given in such a way as not to interfere with the generalplan of this work. 1. The Part Played by Electricity in the Transformation of Chemical Compounds The laws of physical phenomena may be determined, but as we are ignorant of their underlying causes,their interpretation necessarily varies. If the facts do not change, the explanation of them is frequentlymodified. A great theory once accepted is immediately applied to the interpretation of known facts. Thedoctrine of the conservation of energy has for 50 years seemed able to furnish the key to all phenomena. Itis now the theory of electrons for which this role appears to be reserved. By reason of the importance nowgiven to the prevailing ideas on the atomic structure of electricity, it may be interesting to point out theirgenesis.Now dogmas are spontaneous only in appearance. Those who are attracted by a new belief especiallyappreciate its novelty, while it is in reality very old. Its history, generally forgotten by the textbooks, showshow certain ideas grow up and the slow progress of their evolution.It is to the illustrious Davy, about the beginning of the last century, that the srcin of the present ideas onelectrical dissociation, now termed ionization, goes back. Having passes a current through a solution of potash, and having noticed that the potassium went to one of the poles and the oxygen to the other, heconcluded, rightly but much in advance of his time, that the two elements of a compound are charged withdifferent electricities, which are neutralized by combination. The affinity which draws together andassociates the elements of bodies must have its srcin in the attraction of contrary electricities. We do notstate the matter otherwise at the present day.It was on the hypothesis of Davy that Berzelius founded the dualistic theory which governed chemistry for30 years. The compounds called binary, such as acids and oxides, were formed from an electro-negativeunited to an electro-positive element by the attraction of their contrary electricities. The compounds calledtertiary -- that is to say, salts -- came from the combination of an electro-positive base and an electro-negative acid.The dualistic theory vanished when Dumas. Laurent, and Gerhard discovered the phenomenon of substitutions, and showed that in a compound an electronegative element could be replaced by anelectropositive without sensibly changing its properties. Trichloroacetic acid, for example, is acetic acid inwhich three atoms of chlorine (an electronegative element) have replaced three atoms of hydrogen (anelectropositive one). The conceptions of Davy and Berzelius, correct as they were, were abandoned for along period.Their readoption was the consequences of the researches of the illustrious Faraday. Towards 1830, hediscovered the laws of electrolysis, and measured the electric charges given up by bodies at the poles of the battery when they are decomposed by the electric current. He noted that when an electric current ispassed through the solution of a salt, the latter is decomposed into two elements charged with contraryelectricities, which are found at the two poles. This operation, the result of which is to resolve compoundbodies into their elements, is called, as we know, electrolysis. The bodies capable of undergoing such anoperation are called electrolytes. The products of the decomposition constitute ions. Simple bodies,considered as such to be indecomposable, evidently could not be electrolytes and consequently produceions. This last was a fundamental point. Gustave LeBon: The Evolution of Forces ~ Part IIhttp://www.rexresearch.com/lebonfor/evforp2.htm#p2b2ch44 di 10427/04/2014 12:26
