CHEM 207L is a one-credit laboratory course that introduces basic laboratory techniques, quantitative analysis, qualitative analysis, spectrophotometric analysis, gravimetric analysis, stoichiometry, descriptive chemistry and chromatography.   CHEM 207 should be taken concurrently. 

This course, along with CHEM 207, CHEM 209, and CHEM 209L will fulfill the Shepherd University General Studies requirement for eight credits in the Life or Physical Sciences. Specifically this course addresses the following General Studies intended student outcomes:

2.3 Understand cause and effect relationships

2.4 Understand basic scientific concepts and methods

3.5 Utilize tools such as charts, graphs, and equations to represent functional relationships and explain their meaning.




            To learn how to take measurements with precision and accuracy.

            To learn how to use laboratory equipment.

            To learn how to make observations to identify chemical and physical changes.

            To learn how to use a laboratory record book to record observations and data.

            To learn how to analyze data and report results.




            The laboratory manual is required and is available in the bookstore.

            The experiments have been designed with safety as a major consideration. However, the equipment and procedures will be unfamiliar to you and mistakes can and will happen.  Be sure that you understand the hazards associated with the equipment and reagents before starting an experiment.  Do not be afraid to ask questions. SAFETY GOGGLES OR GLASSES MUST BE WORN AT ALL TIMES.   STUDENTS MAY NEVER WORK ALONE IN A LAB.




            You will be able to work much more efficiently in the lab if you read the lab before the experiment.  Be prepared.  The time spent in preparation is time that you won't have to spend in the lab.




            Students are expected to attend all laboratory sessions.  Makeup labs will not be allowed without a valid written excuse.  Labs that are missed with a valid excuse may be made up at a time determined by the instructor or in the last period of the semester.  Students may NEVER work in a lab without permission of the instructor.




            Cheating in all its forms, including plagiarism and cheating on visual work, is considered an academic matter and will result in automatic dismissal from the course and will be recorded on the official transcript.  Using another student’s data for a lab that you missed will result in a zero for the lab.  This dishonesty will also be reported to be recorded on the official transcript.




            All students will need to have a bound lab notebook.   Spiral bound notebooks are not acceptable.  As a preliminary exercise for each lab you should briefly summarize what you will do in the experiment.  Your summary should include a brief (one or two sentence) statement of the purpose of the experiment and the type and number of measurements that you will make.

            A lab notebook is used to keep a record of the work that you do in the lab.  Notebook entries should be complete enough to allow you or someone else to recreate the work that you did in the lab.  Each page should include the date and the name of the experiment.  All entries should be clearly labeled and should have correct units.

            Data should be entered in tables whenever possible.  All tables should have a title and all columns in the table should have titles and units.  All entries in the notebook should be neat and clearly identified.  The best way to make you notebook readable is to make constant reference to the procedures in the instruction book.  The notebook should be signed by the instructor at the end of each lab period.  The notebook will be graded for completeness and clarity. 




            The report sheets that are part of the lab handout can be used as lab reports.  All parts of the report sheet should be filled out unless you are told otherwise.  Some reports include addition questions to be answered.  

            The report sheets are due one week after the completion of the experiment.  There will a 2-point deduction for per day for late reports.  Even if you finish the lab procedure early it is a good idea to stick around and finish as much of the report as possible.  The material will be fresh in your mind and the instructor will be available for assistance.




            Reports and Unknowns                                   90%

            Notebook                                                         10%


            There are no quizzes or tests in this course.  The grade is based on the lab reports, notebooks and unknowns as indicated above.



FINAL GRADE          


The final grade will be based on the following scale


                        A          90 %  to 100 %

                        B          80 %  to  89+ %

                        C         70 %  to  79+ %

                        D         60 %  to  69+ %
