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.

  • NEW ADVANCE STUDY ASSIGNMENTS: Most Advance Study Assignment questions, particularly those with numerical answers, have been changed.
  • APPROPRIATE HEATING BY BUNSON BURNER OR HOT PLATE: Directions for several experiments have been re-written to be agnostic to the use of either hot plates or Bunsen burners in the heating steps. Because Experiment 9, Molar Mass of a Volatile Liquid, poses a potential fire hazard when conducted with Bunsen burners, directions have been re-written to assume this to be the case. Other experiments which necessitate the use of high temperatures, such as those involving the heating of crucibles, or support of combustion tests, remain designed around the use of Bunsen burners.
  • NEW INTRODUCTION TO EXPERIMENT 38: To provide the basis of the confirmatory test for aluminum in Experiment 38, Qualitative Analysis of Group III Cations, the authors have added an introductory section that includes background information on the establishment of the stoichiometry of the aluminum-catechol violet complex as 1:1 in an IB chemistry project carried out by Kendra Pankow, granddaughter of WCW.
  • REDUCED USE OF TOXIC CHEMICALS AND STRONG ACIDS: To accomplish the same chemistry more safely, sodium sulfate replaces sulfuric acid in Experiment 12, The Alkaline Earths and the Halogens. In addition, Experiment 37, Qualitative Analysis of Group II Cations, now uses the organic compound Janus Green as a substitute for mercury(II) chloride to demonstrate the strong reductive capacity of tin(II). With the exception of Experiment 36, Qualitative Analysis of Group I Cations--still included for institutions that want to give their students hands-on experience with the classic separation and identification steps for silver, lead, and mercury(I)—the Eleventh Edition is “mercury-free.”
  • 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. In addition, formal data pages have been added to Experiments 15 and 19.
  • NEW PROTOCOL: The protocol of Experiment 7, Analysis of an Unknown Chloride, now includes not only instructions for the Fajans method with dichlorofluoroscein as an adsorption indicator using diffuse or reflected light, but also instructions for using regular ambient laboratory lighting taking certain precautions.
  • A PROVEN APPROACH: The direct approach of this laboratory manual 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.
  • EXCEL COVERAGE: A section explains how students can use Excel to simplify making calculations, while an appendix describes how to use Excel software in making calculations in several experiments.
  • ADVANCE STUDY ASSIGNMENTS (ASAs): These assignments include sample questions, usually involving calculations, that are similar to those required in processing the data obtained in each experiment. Students who complete the ASAs prior to coming to lab should have no trouble working up the data they actually observe in the lab session. These questions are revised in every edition, especially those containing numerical values.
  • 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.
  • 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.
  • OWLv2 INTEGRATION: Featuring chemist-developed content, OWLv2 is 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. Now with improved student and instructor tools and greater functionality, OWLv2 is more robust than ever. Discover the power of OWLv2 and take learning to a higher level.
