Do the task which is set before you, and do it with a smile. Do not be a time server. Do not use your neighbor's standard solution for accurate determinations. Do not borrow apparatus. Keep your desk and apparatus clean, if you hope to obtain satisfactory results. Always have a towel and sponge in your desk, and use them when you leave for the day. Glass-ware will break if dropped to the floor. Never touch a machine until you are told how to use it. Never run a machine without oil.

Available in PDF, EPUB and Kindle. Book excerpt: Trieste Publishing has a massive catalogue of classic book titles. Our aim is to provide readers with the highest quality reproductions of fiction and non-fiction literature that has stood the test of time. The many thousands of books in our collection have been sourced from libraries and private collections around the world.The titles that Trieste Publishing has chosen to be part of the collection have been scanned to simulate the original. Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original. Imperfections could be in the form of blurred text, photographs, or missing pages. It is highly unlikely that this would occur with one of our books. Our extensive quality control ensures that the readers of Trieste Publishing's books will be delighted with their purchase. Our staff has thoroughly reviewed every page of all the books in the collection, repairing, or if necessary, rejecting titles that are not of the highest quality. This process ensures that the reader of one of Trieste Publishing's titles receives a volume that faithfully reproduces the original, and to the maximum degree possible, gives them the experience of owning the original work.We pride ourselves on not only creating a pathway to an extensive reservoir of books of the finest quality, but also providing value to every one of our readers. Generally, Trieste books are purchased singly - on demand, however they may also be purchased in bulk. Readers interested in bulk purchases are invited to contact us directly to enquire about our tailored bulk rates.

This book was released on 2015-07 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Laboratory Manual of Physical Chemistry In presenting this manual of laboratory exercises in physical chemistry, the authors have been prompted by a threefold object: first, to facilitate the task of the instructor in handling large classes of students beginning a course of practical physical chemistry; second, to assist the student in recording his observations in a clear and comprehensive manner; and third, to present such quantitative exercises as will be particularly desirable in the training of students of engineering. In view of the fact that there are, as a rule, available for laboratory work not more than two and one-half hours at a time, it has been found desirable to have the different pieces of apparatus set up beforehand by the instructor. To this end, each experiment is preceded by an exact list of the apparatus and chemicals needed. It is believed that this will materially aid the instructor in assembling the necessary equipment. At the Rensselaer Polytechnic Institute, the laboratory course immediately follows the completion of the theoretical course in physical chemistry, and students are thus prepared to take up the study of any experiment herein listed. It is therefore found practical to prepare the equipment for one or two units of each exercise before the laboratory course starts, and to shift the student successively from one experiment to another. In this way, an excessive amount of preparatory work is avoided. Many of the experiments have been in use in their present form at this Institute, and elsewhere, for a number of years, and have been found to be thoroughly satisfactory. Directions have been made as concise as possible. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from General Chemistry Laboratory Manual The exercises in this manual are complementary to the author's General Chemistry, Theoretical and Ap plied. The numbering of the chapters and sections follows that of the textbook exactly, as it is expected that students will study both simultaneously. In fact, the exercises can often advantageously precede the corresponding lectures; although in such cases the instructor will find it necessary to give more extended oral instructions at the beginning of the laboratory period than would otherwise be required. Such pre liminary instructions must be given in any event dur ing the early part of the course in order to familiarize the student with the ordinary pieces of apparatus and their manipulation, the regulations and routine of the laboratories and storerooms, and the prescribed system of recording results and submitting them to the in structor for inspection and approval. Oral and written quizzes based on the laboratory work, but involving knowledge of both the laboratory work and the lee tures, will be found helpful.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Laboratory Manual of Chemistry N preparing this brief course, the authors have endeavored to select such work as will best develop the true spirit of investigation. It is not intended to present an exhaustive treatise, but rather a few of the stepping-stones over which the student of this department of nature must travel. We most thoroughly believe that the experiments selected should, as a rule, be of such a nature that the pupil can perform them. For himself. The teacher should be but the guide that points out the right path, calling attention to the by-paths of error. The work here laid out should be accompanied by some text-book. The authors have had in mind, while preparing this work, the Manual of Chemistry, by Eliot and Storer although it could be used with any other good text-book of elementary chemistry. It is our plan to require three hours' work per week in the laboratory and two in the recitation room. The experiments here given, with the necessary practice in determining unknown substances by the Key, will probably occupy the class for forty weeks. Some experiments should be indicated by the teacher for omission, if the time alloted for chemistry is too short.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Elements of Industrial Chemistry The purpose in presenting this elementary work on Industrial Chemistry is to meet the needs of those teachers of the subject who find that the time at their disposal does not warrant the employment of an extended treatise. The author, therefore, has compiled from the Manual of Industrial Chemistry an abridged volume which covers the most salient points of the larger book. The endeavor has been, in arranging this con densation, to treat the subjects covered in a general manner only, thus eliminating as much of the detail as possible in order that the fundamental principles might be more clearly set forth. Although the subject matter is essentially descriptive, a certain amount of theoretical consideration has been included where necessary for the proper understanding of the text. Should the student desire more detailed information on the subject, or a more extended description of the processes under con sideration he is referred to the Manual from which this book is compiled. No claim for originality is made for this volume, and full credit should be given to those who contributed to the larger book mentioned above.

This book was released on 2017-09-12 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Laboratory Manual of General Chemistry A special chapter has been introduced for the study of negative radicals. A differentiation is here made between the reactions of a few special reagents upon compounds before and after heating. Finally, the highly objectionable method of recording in the laboratory those observations which are only to be trans ferred later to a so-called notebook is now eliminated. A student who but once engaged in this indefensible practice is far too prone in later years to record weighings and other data on scraps of paper. When such useless records seem to attain a reasonable degree of satisfaction to his untrained mind he may actually transfer them to a more desirable location, but neither to the credit of the location nor the student. This manual is so constructed that all questions under each heading are consecutively numbered. These same numbers appear also upon the opposite or blank pages and indicate positions for the records. Upon the form and accuracy of these records the student himself must expect the proper estimate of his scientific ability. For the interest and care with which the manuscript has been read by Professor William G. Smeaton of this laboratory and for his many valuable suggestions the author wishes to express his gratitude and appreciation.
