Emil J. Slowinski is an Emeritus DeWitt Wallace Professor of Chemistry at Macalester College. He earned a B.S. degree from Massachusetts State College in 1946 and a Ph.D. in physical chemistry from the Massachusetts Institute of Technology in 1949. He taught at Swarthmore College, 1949-1952; the University of Connecticut, 1952-1964; and Macalester College, 1964-1988. His sabbatical leaves were at Oxford University in 1960 and the University of Warsaw in 1968. He is a co-author, with Bill Masterton and/or Wayne Wolsey, of more than 25 books on various areas of general chemistry. He was actively involved in all editions of CHEMICAL PRINCIPLES IN THE LABORATORY up through the 9th Edition, and though now retired from active writing, still offers insights, advice and support to his coauthors.

Wayne C. Wolsey, an inorganic chemist, received his B.S. from Michigan State University in 1958 and his Ph.D. from the University of Kansas in 1962. He joined the Macalester College faculty in 1965 and is now in "semi-retirement." His last three sabbaticals were spent at the Oak Ridge National Laboratory. In 2001-2002, he investigated various complexing agents for their effectiveness in dissolving calcium oxalate kidney stones, in collaboration with a former student, now a urologist. He has received various awards, including the Minnesota College Science Teacher of the Year in 1989; Macalester's Thomas Jefferson Award in 1993; designation as a MegaMole contributor to Minnesota Chemical Education in 1997; and an award from the Minnesota State AAUP Conference in 2001 for his support of academic freedom and shared governance. He remains professionally active in a number of scientific organizations.

Robert C. Rossi is the Laboratory Supervisor in the Chemistry Department at Macalester College. He obtained a B.S. degree in chemical engineering from the University of Wisconsin - Madison in 1993 and upon graduation joined the Peace Corps, serving in the Fiji Islands. He then taught and carried out applied photoelectrochemistry and semiconductor physics research at the California Institute of Technology, earning a Ph.D. in 2001. After several years teaching as a visiting professor at Carleton College, he moved to Macalester College, where he has been since 2003. In 2011 he became a co-author of CHEMICAL PRINCIPLES IN THE LABORATORY, first writing for the 10th Edition.

  • GOOGLE SHEETS AND EXCEL COVERAGE: Appendix VIII introduces Google Sheets, which is a free alternative to Excel. This section explains how students can use Google Sheets to simplify making calculations. Appendix VII remains for Excel users and describes how to use Excel software in making calculations in several experiments.
  • NEW EXPERIMENT: The 12th Edition features a new experiment, entitled "Fundamentals of Quantum Mechanics," which provides an accessible and hands-on introduction to the concept and general principles of quantized behavior. It was developed to address the steady increase in quantum chemistry coverage in chemistry courses, as this topic has become less exotic and more mainstream, all the while remaining something that few students easily engage with, and for which little accessible lab work has been generally available.
  • ADVANCE STUDY ASSIGNMENTS: These assignments--many revised or updated in this edition--include sample questions, usually involving calculations, that are similar to those required in processing the data obtained in each experiment. Students who complete the ASA's prior to coming to lab should not have any trouble working up the data they actually observe in the lab session.
  • CONTENT UPDATES: Key updates include: mention of safe agitation of the test tube has been added in Experiment 10; the terminology in Experiment 14 now treats "heat" as exclusively an energy transfer, not a property of matter per the debunked caloric theory, and key terms have been changed to "specific heat capacity" and "adiabatic calorimeter"; the text of Experiment 15 has undergone a major overhaul and a figure depicting the "device" has been added to make the experimental approach and calculations more readily understood; and the procedure in Experiment 19 has been streamlined and clarified.
  • ENHANCED EXPERIMENTS: All experiments have been edited to improve the clarity of the instructions and explanations. Careful attention to the scientific units, terminology, and symbology ensures greater consistency with most general chemistry texts.
  • FLEXIBILITY: Labs are easily modified for use as guided inquiry. Each lab gives students a starting point and the information they need to create and conduct the experiment.
  • STUDENT-FRIENDLY: Offering complete coverage of basic chemistry principles, this manual presents topics clearly in an easy-to-understand manner, while requiring students to read and demonstrate understanding of the material.
  • A PROVEN APPROACH: This laboratory manual's direct approach has made it a household name in the General Chemistry laboratory market. Each edition's fully tested experiments are consistently updated to maintain the integrity of this bestselling lab manual.
  • LABSKILLS and PRELABS v2 INTEGRATION: Featuring chemist-developed content, LabSkills PreLabs v2 integrates seamlessly with OWLv2, the most trusted online learning solution for chemistry. With detailed, instant feedback and interactive learning resources, students get the help they need when they need it. Discover the power of LabSkills PreLabs v2 in OWLv2 and take learning to a higher level.
