For courses in Chemistry Laboratory.
With a focus on real-world applications and a conversational tone, this laboratory manual contains experiments written specifically to correspond with Chemistry: A Molecular Approach, 5th Edition by Nivaldo J. Tro. Each experiment covers one or more topics discussed within a chapter of the textbook, with the dual goal of 1) helping students understand the underlying concepts covered in the lecture, and 2) presenting this material in a way that is interesting and exciting.
Updated for the new edition of Chemistry: A Molecular Approach, this manual contains twenty-nine experiments with a focus on real world applications. Each experiment contains a set of pre-laboratory questions, an introduction, a step-by-step procedure (including safety information and a report section featuring post-laboratory questions). Additional features include a section on laboratory safety rules, an overview on general techniques and equipment, as well as a detailed tutorial on graphing data in Excel.
Hallmark features of this title
- Concept-oriented experiments provide varying levels of guidance from and “inquiry-based” appraoch to a classical “cookbook” approach.
- Experiment approaches range from traditional to open-ended and inquiry driven.
- Experiments that general chemistry students rarely perform have been designed to be conducted in a careful, controlled fashion.
New to this Edition
New and updated features of this title
- Safety procedures are outlined and presented as a primary part of the laboratory experience.
- General laboratory equipment and procedures for use in the general chemistry lab are included to prepare students for each lab.
- The graphing data section provides guidance on how to prepare a graph from a given set of data in Microsoft Excel® and emphasizes the importance of data analysis and interpretation.
- Lab experiments 17 and 19C correspond to content on Solids and Modern Materials located in Chapter 12 of Chemistry: A Molecular Approach, 5th Edition.

About our author
Nivaldo Tro has been teaching college Chemistry since 1990 and is currently teaching at Santa Barbara Community College. He received his Ph.D. in chemistry from Stanford University for work on developing and using optical techniques to study the adsorption and desorption of molecules to and from surfaces in ultrahigh vacuum. He then went on to the University of California at Berkeley, where he did postdoctoral research on ultrafast reaction dynamics in solution. Professor Tro has been awarded grants from the American Chemical Society Petroleum Research Fund, the Research Corporation, and the National Science Foundation to study the dynamics of various processes occurring in thin adlayer films adsorbed on dielectric surfaces. Professor Tro lives in Santa Barbara with his wife, Ann, and their four children, Michael, Ali, Kyle, and Kaden. In his leisure time, Professor Tro enjoys mountain biking, surfing, and being outdoors with his family.
