Chemical Lecture Experiments

Excerpt from Chemical Lecture Experiments The demonstration of chemical phenomena on the lecture table, though originally strongly imbued with an element of mysticism inherited from the hermetic art, has always been considered an essential phase of chemical instruction. After chemistry was placed on a broader basis by Lavoisier, and the black art converted to a science, experimental lectures still remained a legitimate factor in presenting the subject. Soon text-books and class recitations and later laboratory exercises for the student supplemented the lecture, and with the introduction of the latter a tendency to neglect the experimental lecture developed. Laboratory exercises, however great their influence in developing the experimental side of teaching the science, have their limitations, experimentally and educationally, and cannot supplant the experimental lecture, for it is in the lecture, and there only, where each experiment stands out clearly defined and unattended by the distractions necessarily accompanying laboratory exercises, that the first accurate observations of chemical phenomena can be made by students. The late Professor Josiah P. Cooke, though one of the first to introduce laboratory exercises into the educational institutions of this country, said, nevertheless, "Experimental lectures are, I am convinced, much the best way of presenting these subjects [Chemistry and Physics] as systematic portions of knowledge."

For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry -- not just to make pretty colors and stinky smells, but to learn how to do real lab work: Purify alcohol by distillation Produce hydrogen and oxygen gas by electrolysis Smelt metallic copper from copper ore you make yourself Analyze the makeup of seawater, bone, and other common substances Synthesize oil of wintergreen from aspirin and rayon fiber from paper Perform forensics tests for fingerprints, blood, drugs, and poisons and much more From the 1930s through the 1970s, chemistry sets were among the most popular Christmas gifts, selling in the millions. But two decades ago, real chemistry sets began to disappear as manufacturers and retailers became concerned about liability. ,em>The Illustrated Guide to Home Chemistry Experiments steps up to the plate with lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab. The bulk of this book consists of 17 hands-on chapters that include multiple laboratory sessions on the following topics: Separating Mixtures Solubility and Solutions Colligative Properties of Solutions Introduction to Chemical Reactions & Stoichiometry Reduction-Oxidation (Redox) Reactions Acid-Base Chemistry Chemical Kinetics Chemical Equilibrium and Le Chatelier's Principle Gas Chemistry Thermochemistry and Calorimetry Electrochemistry Photochemistry Colloids and Suspensions Qualitative Analysis Quantitative Analysis Synthesis of Useful Compounds Forensic Chemistry With plenty of full-color illustrations and photos, Illustrated Guide to Home Chemistry Experiments offers introductory level sessions suitable for a middle school or first-year high school chemistry laboratory course, and more advanced sessions suitable for students who intend to take the College Board Advanced Placement (AP) Chemistry exam. A student who completes all of the laboratories in this book will have done the equivalent of two full years of high school chemistry lab work or a first-year college general chemistry laboratory course. This hands-on introduction to real chemistry -- using real equipment, real chemicals, and real quantitative experiments -- is ideal for the many thousands of young people and adults who want to experience the magic of chemistry.

Excerpt from Chemical Lecture Experiments Owing to the independent nature of each experiment the description is in most instances prefaced with a short state ment of the nature of the reaction finder consideration. The equations have been given as far as practicable, and where the reaction is not regular and the product is of a complex nature, the fact that the equation represents the general reaction only is indicated by its being followed by an interrogation mark enclosed in brackets. To facilitate the preparation of experiments, a list of the apparatus and the chemicals required has been appended to experiments demanding anything not ordinarily found on a lecture table. Just how extensive such a list should be has been a matter of considerable question, and to avoid undue repetition it is assumed that burners, test-tubes, retort stands, pneumatic trough, and such general apparatus, as well as the common reagents, are either on the lecture table or within reach.

Excerpt from Chemical Lecture Experiments: Non-Metallic Elements The object of this book is twofold. Firstly, it is intended to supply chemical lecturers and teachers with a useful repertoire of experiments, suitable for illustrating upon the lecture table the modes of preparation, and the properties, of the non-metallic elements and their commoner and more important compounds. I have therefore given such full directions for the preparation and performance of the various experiments described, as will enable any experimenter to successfully repeat them. No mere description of experiments, however minute, can entirely take the place of experience, but it has been my endeavour throughout this book to give such details, resulting from my own experience, as shall meet as far as possible the lack of experience in others. No account of any experiment has been introduced into the book upon the authority solely of any verbal or printed description, but every experiment has been the subject of my personal investigation, and illustrated in every case, with the exception of three, by woodcuts made from original drawings. What should be and what should not be included under the head of 'experiments suitable for illustration upon the lecture table' may be a matter for difference of opinion, and must depend often upon circumstances.
