Laboratory Experiments for Chemistry: The Central Science in SI UnitsUpplaga 14

For two-semester general chemistry lab courses Introducing students to basic lab techniques and illustrating core chemical principles Prepared by John H. Nelson and Kenneth C. Kemp, both of the University of Nevada, this manual contains 43 finely tuned experiments chosen to introduce students to basic lab techniques and to illustrate core chemical principles. In the 14th Edition, all experiments were carefully edited for accuracy, safety, and cost. Pre-labs and questions were revised and new experiments added concerning solutions, polymers, and hydrates. Each of the experiments is self-contained, with sufficient background material, enabling students 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, although the authors have found in their General Chemistry course that the sequence of Experiments 1 through 7 provides the firmest background and introduction. To assist the student, the authors have included pre-lab questions for the student to answer before starting the lab. The questions are designed to help the student understand the experiment, to learn how to do the necessary calculations to treat their data, and as an incentive to read the experiment in advance.
