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.
