Welcome to the General Chemistry Laboratory!
Contrary to popular belief, the laboratory portion of general chemistry is not designed to torture students. The laboratory is designed to support and illustrate chemical concepts studied in the lecture portion of the course, as well as to introduce important laboratory techniques and encourage analytical thinking. Of course, we cannot perfectly synchronize the coverage of material in the lecture and the laboratory, but we will attempt to make connections whenever possible. Along with concepts and chemistry covered in lecture, the laboratory portion of the course will present some additional chemistry, both theoretical and practical.



This handy periodic table has a molecular mass calculator and allows you to examine periodic trends by color. It is also a jigsaw puzzle! Click on the picture to link to it.

The lab manual contains background information and procedures for the experiments you will perform as part of your Chem 5 and/or Chem 6 course. The pages immediately following contain helpful information about laboratory policies, your lab notebook, the Honor Principle, Safety Regulations, and use of laboratory equipment. Read them carefully before coming to lab the first time and refer to them as the term progresses.

There is a lot of interesting chemistry to explore in the Chem 5 and Chem 6 labs. It is our hope that you will enjoy learning it and that it will enhance your understanding of the material presented in lecture. When you come to lab each week, come prepared, think about what is happening on a molecular level, ask questions, and see what you can learn. What you get out of your laboratory experience will be directly proportional to what you put into it.

Lab Logistics

Eye Protection. You will wear goggles to protect your eyes from splashes. If you wear prescription eyeglasses, you will wear your goggles over your eyeglasses. You must purchase a pair of approved splash goggles from the Chemistry Department Stockroom in 017 Burke before your first lab period. The cost is $9 and exact change is appreciated. Everyone must wear safety goggles for every experiment.

Lab Meeting Places. Each week, you will meet in the assigned classroom at the beginning of the laboratory period (8 a.m. or 2 p.m.) for announcements and a laboratory lecture and/or quiz before adjourning to the labs, Rooms 303-307 Steele.

Lab TA's. At the first meeting you will be assigned to a Teaching Assistant who will supervise your lab work, grade your prelab problems, data sheets, formal reports, examine your notebooks weekly, grade quizzes and evaluate your lab notebook overall at the end of the term. Office hours for your Section's TA's will be announced at your first lab lecture.

Lab Lecture and Prelab Problems. You must attend lab lecture and you must complete the assigned prelab problems and notebook preparation before you come to lab lecture. You must turn in your solutions to the prelab problems to your TA's box at the front of the lecture hall before the start of lab lecture or you will not be permitted to continue the lab assignment and you will not be permitted to make up the lab. If you are late to lab lecture, you will not be permitted to do the lab assignment and you will not be permitted to make up the lab.

Laboratory Charges. A fee for your lab notebook and for expendable laboratory supplies will be charged to your College bill. Additional charges will be made for excessive damage.

Laboratory Manual. Before the first day of lab, you must purchase a laboratory manual from Wheelock Books. The cost of the manual is approximately $10. There will not be any copies available in Burke or Steele. Be sure to buy this term's lab manual and do not use an old one, as changes are made each term.
