• Emil J. Slowinski

  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

  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 Rossi

  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.

• ENHANCED EXPERIMENTS: All experiments have been extensively revised to improve the clarity of instructions and explanations, and to simplify procedures and math where possible. Non-essential technical terms have been removed or made less central, and essential ones are carefully explained.

• ACCESSIBLE ELECTROCHEMISTRY: The 13th Edition features electrochemistry experiments rewritten to make the topic more understandable for beginning students. It also places greater value on clarity and comprehension over dense coverage of every nuance of this complicated subject.

• LAB TECHNIQUE UPDATES: Expanded appendices provide practical information and guidance about laboratory techniques derived from experience. Experiment instructions have been made more flexible with respect to equipment, such as heat sources and filtration apparatus, while continuing to provide detailed guidance useful at the time of the experiment.

• PhET RESOURCES FOR VIRTUAL LEARNING: Assignments in WebAssign which leverage PhET simulations provide opportunities for your students to engage with concepts outside of time spent in a physical lab space.

• FLEXIBILITY: Many experiments are easily modified for guided inquiry. Each lab gives your students a starting point and the information they need to create and conduct the experiment. The experiments are now designed to be independent of one another, so you can select the experiments that support your learning goals.

• PROVEN APPROACH: This manual's direct approach has made it a successful general chemistry lab manual over several editions. The fully tested experiments are consistently updated to maintain the integrity of the manual.

• STUDENT-FRIENDLY: Offering complete coverage of basic chemistry principles, this manual presents topics clearly and in an easy-to-understand manner, while also requiring students to read and demonstrate understanding of the material.

• DESIGNED FOR SUCCESS: Each experiment has been optimized for your students to achieve learning outcomes. Extensive, detailed appendices walk students through many of the fundamental skills critical for success, from using a centrifuge to analyzing data.

• ADVANCE STUDY ASSIGNMENTS: These assignments, now available in WebAssign, include sample questions, usually involving calculations, similar to those required in processing the data obtained in each experiment. Students who complete the ASA prior to lab should be well-positioned to work up the data they observe in the lab session.

• COMPLETE INSTRUCTOR’S GUIDE: The Instructor’s Manual contains not only the solutions to the Advance Study Assignments, worked out in detail, but analyzed sample data, detailed setup instructions, cost and sourcing information, and practical advice to help you get the best out of each experiment.

• LABSKILLS PRELABS INTEGRATION: Available in WebAssign, LabSkills modules prepare students for the lab experience virtually by focusing on lab technique, measurement and chemical reactivity through interactive simulations and auto graded quizzes. Detailed and instant feedback give students the help they need when they need it.
