Laboratory Inquiry in Chemistry , Third Edition (Brooks Cole Laboratory Series for General Chemistry)

LABORATORY INQUIRY IN CHEMISTRY teaches you the skills you need to easily complete your laboratory investigations. Each investigation begins with a scenario that puts a real-life spin on the problem at hand, provides you with a sense of why the project is relevant, and creates a scenario that is comparable to what chemists face in the real world. Completing experiments is easy with a list of goals, materials, reagents, guidelines, and hints found at the beginning of each investigation.
