††††††††††† CHEM 209L is a one-credit laboratory course covering basic experimental techniques, quantitative analysis, acid base chemistry, electrochemistry, qualitative analysis, synthesis, kinetics, equilibrium and spectrophotometry.


This course, along with CHEM 207, CHEM 209, and CHEM 207L 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.

CHEM 207, CHEM 207L, CHEM 209 should be taken concurrently.




††† ††††††† 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 understand what it is you are trying to do.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 available without a valid written excuse.Labs that are missed with a valid excuse may be made up at a time determined by the instructor.Students may NEVER work in a lab without permission of the instructor.Students may never work alone in a laboratory.




††††††††††† 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.






The primary purpose of a lab notebook is to have a complete record of what you did in lab.In principle, you should be able to use the combination of the written lab procedure and the lab notebook to figure out exactly what happened in an experiment.The notebook entries need to be complete enough so that another person should be able to reproduce your work using this information.If you were to lose a lab report you should be able to completely reproduce it based on the information in the notebook.The notebook is placed where you first write all data and record all observations.




The lab notebook should be a bound notebook, not a loose-leaf binder or a ring binder.†† When you start a new notebook, use a pen to number each page from the first page through about fifty pages.Put the number in the upper, outside corner of each page.Never remove pages from this notebook.All entries should be in pen.All entries should start on the first page and then continue on consecutive pages.


On the first page, put your name and course number .You may want to put you address and/or phone number here in case your book is lost.


††††††††† In your notebook, each lab exercise should start on a new page.The first page for each experiment in the notebook should have the following at the top of the page:


Title of experiment,date,partners names (if applicable).Each addition page used should have the date and the title.


Always write in pen.If you have mistakes put a single line through the part in error.You should still be able to read the original entry since people sometimes cross out things that they later realize were correct.All data collected in the experiment should be written first in the notebook.Donít worry about having a perfectly neat and clean notebook.A real lab notebook never looks impeccably neat and clean because, if it is used correctly, it will probably be stained and have a fair amount of crossed-out data.††




††††††††††† All data should have appropriate units and an appropriate number of significant figures.For example, the weight of a penny on an analytical balance should be reported as 2.5345 g.If the weight had been 2.5000 g it should be entered with four decimal places.2.5 g does not mean the same thing.It is usually best to organized data into a table if possible.In that case the units can be placed at the top of the column.



††††††††††† You do not have to write the complete procedure for every part of the experiment.You can assume that the details are in the lab manual. However, any changes in procedure from those in the manual should be indicated.All data and observations should be written directly into the notebook.This information should be easily correlated with the lab procedure as written in the manual.It is often easiest to organize data if you prepare a table in the notebook before starting the experimental work.




††††††††††† Although not required, it is good practice to include some sample calculations in the notebook.


Graphs and Charts etc.


The graphs or charts that you include in your reports can be duplicated and included in the notebook if you want.Do not staple the report sheets into the notebook.All of the information on the report sheet should already be in the notebook.




††††††††††† You may include answers to questions for the lab report in the notebook but this is not required.




††††††††††† The report sheets that can be torn out of the lab manual will be used as lab reports.All parts of the report sheet should be filled out unless you are told otherwise.Many reports include 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.
