Textbook

University of Hawaii CHEMISTRY 162L Experiments

Supplies

You are expected to provide yourself with safety glasses or goggles, proper attire, and a laboratory notebook.

Safety

No one will be permitted to work in the lab without safety goggles, closed toed footwear (no slippers, sandals, etc.), and long pants. No food or drinks are permitted in the laboratory. It is important that you report any accidents, no matter how minor, to your TA. No one is permitted to work in the lab without a TA present. Waste disposal must be done properly.

Introduction to the Laboratory

Chemistry 161L is a general chemistry laboratory course. You are expected to attend all meetings of the course and to complete all assignments on time. There will be no make up laboratories. You may be excused from a single laboratory period during the quarter, but only under extraordinary circumstances. An unexcused absence counts as a "ZERO" for that lab period.

Each week you will carry out an experiment during the laboratory period. Before lab you will be expected to have read the description of the experiment, written up a working procedure for the experiment in your laboratory notebook, and be familiar with the general topic(s) to be investigated. Beginning in the second week of classes a short written quiz over the material of the previous lab and the current lab will be given at the start of each lab period.

PLAN AHEAD. You will often encounter delays. Organize your work so that these delay times are not wasted. Keep your work area clean - sloppy work is rarely accurate or precise.

The Laboratory Notebook

The laboratory notebook is an important part of this course because it is the complete record of everything you do. Your notebook should meet the basic requirements of any research or control laboratory. The notebook should be bound and each page sequentially numbered. Square rule paper is convenient for tables and graphs. It must begin with a Table of Contents that lists each experiment and corresponding page numbers. A carbon copy notebook is required for this course.

All entries in a laboratory notebook must be made in ink, with errors or data to be ignored neatly lined out, never erased or scratched out. A neat, well-organized, and easily read notebook will make your TA happy, but the primary purpose is to compile a complete record of your original data and calculations. Enter all data immediately into your notebook - not on loose pieces of paper that may be lost or confiscated. A uniform format is essential in your laboratory notebook. This is important because it aids in the organization of your reports and lab work; furthermore, it allows sections to be turned in for grading at the appropriate time. Use the following format:

Page Header

Include a block of the following information on every page:

Title of Experiment:

Your Name:

Partner's Name (if any):

Date Performed:

Overall Outline for a Given Experiment

I. Purpose

One or two sentences which state the essence of the experiment: include the method and species that is being determined.

II. Procedure

This should include a numbered, ordered list of the tasks to be accomplished in the experiment. You should be able to run the experiment with only this procedure. A flowchart is suggested in addition to this list.

III. Data

Clearly record all data from the experiment. This includes, but is not limited to: the unknown identification number, a physical description of the unknown, tabulated measurements, etc.

IV. Conclusions

Explain any trends or anomalies in the data in this section. Support the discarding of any results and analyze your experimental errors. Suggestions for the modification of the lab procedure should be included in this section. List observations of unexpected, inconsistent, and interesting results. Attach the carbon copy of your conclusions to your lab report.

Due Dates

At the beginning of a lab session the report and conclusions from the previous lab session are due. Later in the labs session, after the quiz and pre-lab lecture, purpose and procedure sections for the current lab session are due. Finally, at the conclusion of a lab session, the data section for that lab session is due. The penalty for late lab reports is one point for each weekday after the due date.

Quizzes

A short quiz will be given at the beginning of each session that will cover material from the previous lab session and the current lab session. In general, the student is expected to know the underlying principled of the methods used - both the chemistry and the instrumentation.
