Excerpt from A Guide to Elementary Chemistry for Beginners I know of but one way to teach a student how to acquire a real knowledge of nature, and that is, to fix his mind habit ually on things and events brought under his own eye, and direct him to the discovery of facts and principles for himself. The use of apparatus is, of course, indispensable if the student is thus to study phenomena instead of descriptions of phenomena, and the use of apparatus, by himself, is with out doubt the method which is most certain to stimulate his mind to the greatest activity. Laboratory study for students in high schools is rapidly growing in favor, but unfortunately, in many schools where chemistry is taught, the difficulties in the way of this method are still thought to be real. Even in these, chemistry to be truly useful should be presented as a study of phenomena, by experiments, instead of what some body has said about phenomena in books. I have therefore tried to construct a course of experiments suited to the use of the beginner, at his laboratory desk, and to the use of the teacher for his class of beginners, where facilities for students to work for themselves seem to be out of reach.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1886 edition. Excerpt: ... agree with these in being soft, light, and combustible on water. Yet in some things they do agree quite closely. For example: Potassium forms the oxide K20 Copper" "Cu2O Silver" "Ag2O In these compounds the atoms of potassium, copper, and silver hold the same relation to oxygen. And the order of their atomic weights brings them together in the same group in the spiral. The Vacant Places.--There are many vacant places in the spiral: what is the meaning of these gaps? They lead us to think that the elements are not yet all discovered. When the table was first made there was a vacant place where gallium, Ga, now stands in the third group. Mendelejeff said that there ought to be an element whose "atomic weight is about 69, its specific gravity about 6, and its atomic volume about 11.5," to fill this gap. Afterward gallium was discovered. Its atomic weight proved to be 69.8, its specific gravity 5.9, and its atomic volume 11.8. From its vacant place in the table, Mendelejeff was able to give the properties of this metal before it had been discovered. He did the same thing for the element scandium, Sc, also in the third group. Possibly other elements are yet to be discovered by which other gaps will be filled. the analytical system. Classification Founded on Solubility.--We have found that hydrochloric acid will give a precipitate if mixed with a solution of a compound of silver, Ex. 193, but none if mixed with a solution of a compound of copper, Ex. 185. This is because silver chloride is insoluble in the liquid used, while copper chloride is soluble. Now all metals whose chlorides are insoluble, like that of silver, can be put with silver to form one group. Such differences in solubility throw the metals together into classes called the...

Excerpt from Elementary Chemistry Preliminary Statement. If we observe nature closely, we shall soon see that two quite different classes of changes are constantly taking place. First, there are the changes which do not affect the essential character of things: like the motion of a body from one Spot to another, and the variations between heat and cold, sound and silence, light and darkness, and so on. Secondly, there are the changes which substances undergo in their innermost structure: like the transformation of wood into charcoal, of the constituents of soil and air into the stems and leaves of plants, and a multitude of other simi lar alterations of different degrees of complexity. Changes of the first class are called physical changes, while the others are known as chemical; and it is with the latter that the science of chemistry has to do.

Excerpt from Elementary Modern Chemistry The beginner in the study of chemistry finds interest and pleasure, first of all, in the remarkable new facts which are placed before him, and this is both natural and desirable. N 0 one can master the science without much study of proper ties and reactions, and minute acquaintance with as many phenomena as possible is a fundamental requisite. Modern chemistry has, however, a number of general laws which appear. Everywhere through it, connecting various facts in the most interesting way. Before study has gone very far it becomes necessary to begin the statement of these laws and to indicate how the facts already learned group them selves about them. Two purposes are served by this method of presentation. First, a real science of chemistry begins to unfold itself to the student, and second, the acquisition of more new facts is made easier and more interesting. We have planned in this book to present a sufficient number of facts and experiments to fill the time usually devoted to a first course, and at the same time we have endeavored to fit these facts, as far as possible, to the Simpler of the general laws now firmly established as the basis of the science of chemistry.
