Slowinski/Wolsey/Rossi's CHEMICAL PRINCIPLES IN THE LABORATORY, 13th Edition, maintains the high-quality, time-tested experiments and techniques that have made this student-friendly resource a perennial bestseller. Continuing to offer complete coverage of basic chemistry principles, the topics are presented in a direct, easy-to-understand manner. This edition revises every experiment to make the language simple, clear and current, while maintaining a friendly and accessible tone. Mathematical and laboratory procedures have been simplified and shortened, where possible, in light of the increasing time pressures that are faced in lab courses.

WebAssign Features

  • Read It links under each question quickly jump to the corresponding section of a complete, interactive eBook that lets students highlight and take notes as they read.
  • Course Packs with ready-to-use assignments were built by subject matter experts specifically for this product to save you time, and can be easily customized to meet your teaching goals.

WebAssign Question Types

  • 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.
  • Concept Questions (CQ) are used in pre-lab assignments that include questions and exercises specifically written to tie chemical concepts learned in lecture to the laboratory experiments.
  • The Advance Study Assignments (ASA) 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.
  • PhET Simulation Tutorial questions leverage linked PhET simulations and provide opportunities for your students to engage with concepts outside of time spent in a physical lab space.
