All modern chemistry is founded on this principle; and laws like the law of multiple proportions, introduce an evident discontinuity to which we find analogies in the law of electrolysis.
In the electrolysis of a 0.8000 gram sample of brass, there is obtained 0.0030 gram of PbO , and a deposit of metallic copper exactly equal in weight to the ignited precipitate of Zn P O subsequently obtained from the solution. What is the percentage composition of the brass? !Answers!: 69.75% Cu; 29.92% Zn; 0.33% Pb. !Answer!: 2.48 cc. !Answer!: 0.83 cc. !Answer!: 0.0152 gram.
As experiment has shown, in all the circumstances where it has been possible to effect measurements, the equality of the charges carried by all corpuscules, ions, atoms, etc., we ought to consider that the charge of the electron is here, again, that of a univalent ion in electrolysis, and therefore that its mass is only a small fraction of that of the atom of hydrogen, viz., of the order of about a thousandth part.
Not the spark from an induction coil or Leyden jar, but a strong and steady current at a low pressure, is adapted for electrolysis or electrodeposition, and hence the voltaic battery or a special form of dynamo is usually employed in this work.
It has also suggested and, moreover, still daily suggests researches of the highest order. In the first place, the theory of Arrhenius explains electrolysis very simply.
Personally, I don't think Pearcy himself was resistant. Perhaps Minturn was not, either. At any rate, after Pearcy's death, it was I who advised Minturn to take the electrolysis cure in New York. I took him down there," added Gunther. "Confound it, I wish I had stayed with him.
For these were thin sheets of nickel, printed by the electrolysis process. "Just a sheer streak of luck," Stern remarked, as he stood looking at this huge piece of fortune with the girl. "Just a kindly freak of fate, that Van Amburg should have bought one of Edison's first sets of nickel-sheet books.
It has been supplanted by the electrical current in some of the most beautiful and useful phenomena of our time. Electrolysis is the name of the process by which fluid chemicals are decomposed by the current. A familiar early experiment in electrolysis is the decomposition of water a chemical composed of oxygen and hydrogen, though always thought of and used as a simple, pure fluid.
He applied the term Electrolyte to every substance which can be decomposed by the current, and the act of decomposition he called Electrolysis. All these terms have become current in science. He called the positive electrode the Anode, and the negative one the Cathode, but these terms, though frequently used, have not enjoyed the same currency as the others.
The motion of the armature in both of these instruments takes a sensible time, but Alexander Bain, of Thurso, by trade a watchmaker, and by nature a genius, invented a chemical telegraph which was capable of a prodigious activity. The instrument of Bain resembled the Morse in marking the signals on a tape of moving paper, but this was done by electrolysis or electro-chemical decomposition.
