ELECTROLYSIS, WATER PURIFICATION, ELECTROPLATING DECOMPOSING LIQUIDS.--During the earlier experiments in the field of electricity, after the battery or cell was discovered, it was noted that when a current was formed in the cell, the electrolyte was charged and gases evolved from it.
A similar action takes place when a current of electricity passes through a liquid, with the result that the liquid is decomposed--that is, the liquid is broken up into its original compounds.
Thus, water is composed of two parts, by bulk, of hydrogen and of oxygen, so that if two electrodes are placed in water, and a current is sent through the electrodes in either direction, all the water will finally disappear in the form of hydrogen and oxygen gases.
MAKING HYDROGEN AND OXYGEN.--During this electrical action, the hydrogen is set free at the negative pole and the oxygen at the positive pole.
A simple apparatus, which any boy can make, to generate pure oxygen and pure hydrogen, is shown in Fig. 89.

What does chapter 13 of Electricity for Boys contain?

Chapter 13 holds 85 sentences of Electricity for Boys, unabridged, divided into 17 reading sections.

This page carries chapter 13 of Electricity for Boys by James Slough Zerbe exactly as it stands in the source edition, without abridgement. It runs to 85 sentences, grouped into 17 sections of at most 5 sentences so that a reader can take the chapter in steady, finishable pieces. The chapter also stores a coverage record mapping every one of its sentences to a part of the work, which is how the edition demonstrates that no line was dropped.

How do I study chapter 13 of Electricity for Boys?

Work through the 17 sections in order, replaying any sentence and tapping unfamiliar words for their entries.

Each of the 17 sections in this chapter is short enough to read once, hear once, and then re-read with the vocabulary in view. Tapping a word plays it alone and opens its dictionary entry with IPA, part of speech and meaning, so the reader is never forced to guess a pronunciation from spelling. Working section by section keeps a long chapter from becoming an undifferentiated wall of text, which is the usual reason a reader abandons a work of this period.

Can chapter 13 be read aloud to me?

Yes — every sentence and every individual word in chapter 13 can be played aloud in United States English.

Audio covers the whole chapter: any sentence can be played, and any single word within it can be played on its own. The voice uses United States English. For a work of this period that matters, because spelling is an unreliable guide to pronunciation for vocabulary that has fallen out of daily use, and a learner who guesses wrong tends to keep the error. Hearing the word in its own sentence, and then alone, settles it.
