Synopsis

This manual contains 43 finely tuned, self-contained experiments chosen to introduce basic lab techniques and to illustrate core chemical principles. The Eleventh Edition has been revised to correlate more tightly with Brown/LeMay/Bursten’s Chemistry: The Central Science, 11/e and now features a guide on how to keep a lab report notebook. Safety and waste management are covered in greater detail, and many pre-lab and post-lab questions have been updated. The labs can also be customized through Catalyst, Pearson's custom database program.

About this title

About the Author

Presenting a total of 41 finely tuned experiments that have been tested by thousands of students, this comprehensive manual teaches students basic laboratory techniques, reviews chemical concepts, helps students identify different chemical substances, and helps students learn to think like scientists.

Each experiment:

• States learning objectives
• Lists apparatus and chemicals needed for that particular experiment
• Describes what the experiment will prove
• Highlights and safety disposal information
• Provides step-by-step procedures
• Poses preliminary questions and emphasizes important take-away points
• Concludes with report sheets for answering questions and tabulating results

Most students who take freshman chemistry are not planning for a career in this discipline. As a result, the introductory chemistry course usually serves several functions at various levels. It begins the training process for those who seek to become chemists. It introduces nonscience students to chemistry as an important, useful, and, we hope, interesting and rewarding part of their general education. It also should stimulate those students who are seeking the intellectual challenges and sense of purpose they hope to obtain from a career.

This manual has been written with these objectives in mind and to accompany the ninth edition of the text Chemistry: The Central Science by Theodore L. Brown, H. Eugene LeMay, Jr., and Bruce E. Bursten. Each of the experiments is self-contained, with sufficient background material to conduct and understand the experiment. Each has a pedagogical objective to exemplify one or more specific principles. Because the experiments are self-contained, they may be undertaken in any order; however, we have found for our General Chemistry course that the sequence of Experiments 1 through 7 provides the firmest background and introduction.

To assist the student, we have included review questions to be answered before the experiments are begun. These are designed both to help the student understand the experiment and as an incentive to read the experiment in advance. As a further incentive, answers to some of these questions are provided in Appendix J.

We have made an effort to minimize the cost of the experiments. We have at the same time striven for a broad representation of the essential principles while keeping in mind that many students gain no other exposure to analytical techniques. Consequently, balances, pH meters, and spectrophotometers are used in some of the experiments. A list of necessary materials is given at the beginning of each experiment.

Each of the experiments contains a detachable report sheet that is easily graded, and most experiments contain unknowns. Very few of the experiments may be "dry-labbed."

In this ninth edition we have:

• carefully edited all experiments for accuracy, safety, and cost
• expanded experiment 1 to include a density measurement
• added more instructions about waste disposal
• added more helpful hints to instructors in the Annotated Instructor's Edition (AIE)
• modified many of the review questions
