EXPERIMENTS IN GENERAL CHEMISTRY, Sixth Edition, has been designed to stimulate curiosity and insight, and to clearly connect lecture and laboratory concepts and techniques. To accomplish this goal, an extensive effort has been made to develop experiments that maximize a discovery-oriented approach and minimize personal hazards and ecological impact. Like earlier editions, the use of chromates, barium, lead, mercury, and nickel salts has been avoided. The absence of these hazardous substances should minimize disposal problems and costs. This lab manual focuses not only on what happens during chemical reactions, but also helps students understand why chemical reactions occur. The sequence of experiments has been refined to follow topics covered in most general chemistry textbooks. In addition, Murov has included a correlation chart that links the experiments in the manual to the corresponding chapter topics in several Cengage Learning general chemistry titles. Each experiment--framed by pre-and post-laboratory exercises and concluding thought-provoking questions--helps to enhance students' conceptual understanding.
- Labs have been updated with the most recent data and values in order to accurately reflect the changes in lab courses.
- The new Activity 35 adds additional challenges and experiments, and Activity 36 provides exercises that develop graphing skills.
- An Online Instructor's Manual contains resources designed to streamline and maximize the effectiveness of course preparation. It includes a list of chemicals and quantities required for each experiment per student and solutions to Pre-Lab problems.
- Murov focuses not only on what happens during chemical reactions but also helps students understand "why" chemical reactions occur.
- Each experiment includes pre-laboratory exercises and thought-provoking questions (with answers to selected questions).
- Review Exercises, found at the end of the manual, help students test their understanding of key concepts and synthesize the material they have learned.
- A number of experiments include post-laboratory exercises and conclude with a set of review exercises.
- A procedure for following the visual clock reaction spectroscopically, instead of visually, is included in the kinetics experiment. This also provides a link between the equilibrium and kinetics experiments.
- As with the previous editions, the use of chromates, barium, lead, mercury, and nickel salts has been avoided, effectively minimizing disposal problems and decreasing costs.
- A correlation chart links the experiments to corresponding chapter topics in several Cengage Learning general chemistry titles, including Kotz, Masterton, Moore, and Whitten.
