Succeed in chemistry with CHEMICAL PRINCIPLES IN THE LABORATORY, Tenth Edition! Clear, user-friendly, and direct, this lab manual provides you with the tools you need to successfully complete lab experiments and lab reports. Analyzing the data you observe in the lab sessions is easy with the manual's numerous Advance Study Assignments that give you extra practice with processing data through sample questions.

Features and Benefits

  • GREENER EXPERIMENTS. Four experiments have been made greener by reducing volume and toxicity. This not only benefits the environment, but also reduces the cost of the experiments overall.
  • 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.
  • 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.
  • 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.
  • 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.

Author Bio

Emil 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.
