Excerpt from Chemical Experiments General and Analytical: For Use With Any Text-Book of Chemistry, or Without a Text-BookIn preparing the experiments the author has endeavored, first, to select such as are most instructive and best illustrate the subject without being too elaborate, second, to arrange them in an order calculated to lead up by the most natural and easiest steps to a knowledge of the science, third, to make the subject fascinating by giving just enough information and suggestion to interest the experimenter, and to make him work for the knowledge to be gained. Finally, the author has aimed to make the book simple enough fer the dull and slow pupil, and - by the introduction of supplementary and original work elaborate enough for the most acute. Great care has been taken to give minute and accurate directions for performing the experiments. Terms at the end of experiments are for pupils to study outside the laboratory, and are often repeated. They may also be discussed in the laboratory.Metal analysis has received a somewhat unique treatment. Each metal of a group is first taken separately, and the analytical reactions are given. This method shows the pupil at once why a given reagent is added, and what its effect is. The product is given when the substance is in solution as well as when it is precipitated. The group is next treated in the same way. This method clarifies the subject greatly in the pupil's mind, and is believed to be a valuable departure in teaching analysis.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
