Text:                                       Fundamentals of Analytical Chemistry 8th ed., Douglas A. Skoog, Donald M. West, F. James Holler and Stanley R. Crouch, Publisher:  Brooks/Cole Pub Co - REQUIRED

Laboratory Manual:            An "in-house" lab handout containing experimental protocols for the laboratory experiments will be provided. Protocols for some of the experiments are contained in the last chapters of the lecture text.

Course:                                 An intensive laboratory experience which applies the principles developed in lecture in Quantitative Analysis, CHEM 3250. Most of the analyses will be performed through common "wet" techniques such as classical gravimetric and volumetric analysis and will be quantitative in nature rather than qualitative. In other words, you will already know what species is present in a sample and the focus will be on the quantification of the amount of a species present in a given sample. You will be required to maintain a laboratory notebook for your experimental procedures, data manipulation and results. The course grade will be based on the accuracy with which you can determine the concentrations in your samples as well as the documentation in your laboratory notebook.

Goals:                                    In this laboratory course you will learn and apply the techniques necessary to complete analyses using various analytical methods.  You will also develop an appreciation for record keeping, cleanliness, accuracy, and precision in laboratory analysis.

Attendance:                          Two, 3-hour laboratory sessions. You are expected to attend daily as your grade is based on your laboratory performance. You must complete your lab experiments before the due dates.

Grading:                                Your grade on each experiment will be based on the percent relative error of your experimental determination of concentration versus the actual concentration in each sample. Experiment results will be required by dates posted in the laboratory.  Each day past the deadline will result in a deduction of 10 points from the grade earned on the experiment.  Grading on percent relative error is as follows:

The lowest grade of all of the experiments will be dropped from the final grade calculation.  The final grade will be based on the average of the remaining experimental grades and the laboratory notebook.

Average lab grade               =              90%

Notebook grade                   =              10%

The following grading scale will be used:

Chemistry Lab Requirements:

                                                The dress requirements described in "Safety in the Laboratory," pages 52-53 of the textbook as well as the GSW Chemistry Lab Requirements, will be enforced during laboratory periods. You must provide your own: calculator, pen, pencil, bound notebook (See pages 51-52 of the textbook).

Student Disability Statement:

A student requesting classroom accommodations or modifications due to a documented disability must notify me within the first two weeks of the semester.  The student has not already done so, he or she must contact the Office of Student Support Services located in room 304 of Sanford Hall.  The phone number is 229-931-2294.”  Failure to do so will result in grade penalty or medical withdraw. The disability must be documented by the University approved institutions.

Excused Absences:              a) Involved in an official university activity if a statement verifying participation is provided
b) Due to illness or accident if a physician's statement is provided
c) Other valid emergency, such as a death in the immediate family with documentation

Valid emergencies must be brought to the instructor's attention within two days. The official method of communication between you and the university is the GSW email account. Thus, it is crucial to check your accounts frequently.

Make-up Policy:

You are allowed to have only one make up lab and a University–approved excuse is required in order to take the makeup. With sufficient reason and early notification I will occasionally give an individual the lab earlier.

Integrity:                               All dishonest academic behavior will be prosecuted. (See the GSW Bulletin.) Cheating on an assignment will result in a grade of zero or possibly an F for the course. The homework may involve group work, but plagiarism is not acceptable. All work that you turn in must be your own work. It’s possible that this course will involve the use of plagiarism-prevention technology. You may, for example, be required to submit written assignments on-line through a plagiarism-prevention service or to allow me to submit copies of your writing to such a service. The written assignments may then be retained by the service for the sole purpose of checking for plagiarized content in future student submissions. If a violation occurs before the last day to withdraw without penalty for the term, you will receive as the final grade a grade of F for the class regardless of whether you attempt to withdraw.

Cell phones:                         Cell phones are not allowed in class. Students are not allowed to go into the hallway to answer their phones during class time. A student whose cell phone rings or vibrates in class will be asked to leave. The only time students are allowed to check their phones is in the event of the campus emergency warning sirens going off. Texting in class will not be tolerated.  If you are found to be texting in class you will be required to speak with the departmental chair.  If it happens again, you may be administratively withdrawn from class.  If any serious circumstance (i.e. - law enforcement, critical medical condition of a relative) should require you to be on call, you should notify me before class.
