Introduction:
With today's familiar cry by students for relevance in course work, analytical chemistry stands out
as one example of a practical and useful subject. Chemical analysis is used in many fields of science,
clinical, biochemist's, physiologist's and the engineer's laboratory. It is an intrinsic tool in geology,
oceanography, air and water pollution. Rare is the chemist who does not rely frequently upon analytical
chemistry for the solution of problems.
The wide utility of analytical chemistry is sufficient reason alone for treating it as an individual
course. Another reason, nearly as important, is that the analytical course is one of the few where the
student learns careful and quantitative laboratory skills and techniques. The skills are critically important
for the environmental technician, physician, dentist, pharmacist, forensic scientist, quality control
technician and for those in many other professions. Analytical chemistry becomes a little more exciting
when the student realizes that an incorrect blood analysis may endanger a patient's life, or that an error in
quality control analysis may result in serious financial loss for manufacturer.
Objectives:
The major objective of this course is to provide a rigorous background in analytical chemistry.
The secondary goal is to develop in you the student an appreciation of the difficult task of judging the
accuracy and precision of experimental data and to show how these judgments can be sharpened by the
application of statistical methods. The third aim is to introduce the student too wide range of techniques of
modern analytical chemistry. The final goal is to teach the laboratory skills that will give students
competence in their ability to obtain high-quality analytical data.
Major Learner Outcomes:
At the completion of Chemistry 5, the students are expected to develop the knowledge and comprehension
of the core concepts of Analytical Chemistry.
The students will have developed a set of fundamental skills that can be applied to various analytical
situations. These skills will include the following:
A. Problem-solving skills. Students that complete this course will be competent problem-solvers. They
will be able to identify the essential parts of a problem and formulate a strategy for solving the problem.
They will be able to estimate the solution to a problem, apply appropriate techniques to arrive at a solution,
test the correctness of their solution, interpret their results and connect the solution to related areas science.
B. Experiential learning skills (laboratory skills). The students that complete this course will
demonstrate that they are competent experimentalists. They will be able to design and set up an
experiment, collect and analyze data, identify sources of error, interpret their results and connect it to
related areas of science.
C. Computer skills. The students will demonstrate they are competent users of basic computer software,
such as word processing, spreadsheet, data acquisition, graphing programs and be able to perform internet
searches.
D. Presentation skills. The students will express (orally and in writing) their understanding of core
principals, the results of experiential learning activities (laboratory experiments, field work), and their
analysis of problems.

DISCUSSION/LECTURE:
You are required to attend all the discussion/lectures. Attendance will be taken each time.
Excessive absences will result in poor performance, fewer points obtained and a lower final grade in
this course.
A daily lecture and laboratory schedule is attached as an addendum to this document.
Quizzes:
A group or individual quiz will be given during discussion/lecture session each week (don’t be
late). Each learning activity/quiz will be worth 10 points. Activities/questions will be based on the
material presented between activities/quizzes and may include the laboratory work. It is important,
therefore, that you stay current in both reading, homework and laboratory work.
Make-up
activities/quizzes will NOT be given. At the end of the semester one activity/quiz will be removed
from the total (i.e. lowest score will be omitted).
EXAMS:
There will be Three Comprehensive Problem Mid Term Exams (75 pt's each), One FINAL
COMPREHENSIVE EXAM (125 pt's) given during the semester. The exams will be given during the
weeks and on the particular days noted in the attached schedule. The material to be covered on each exam
is noted on the schedule. The mid term exam’s will be a mix of in class (25 pts) and take home (50 pts)
the take home portion will be due before the in class portion begins. The final exam will be a mix of in
class (50 pts) and take home final to be turned in before the in class portion of the final begins.
Make-up exams will not be given.
LABORATORY INFORMATION:
Chemistry is an experimental science. Therefore, Chemistry 5 laboratory sessions are a extremely
important and integral part of the Chemistry 5 course. Class attendance and laboratory work are required.
Each student is automatically registered for the laboratory section. Each section will meet twice a week.
The laboratory exercises are designed and scheduled to help you correlate and comprehend the material
presented in discussion/lecture that week. In light of this, the information gleaned from laboratory
experimentation is fair material for exams and quizzes. If you cannot attend a laboratory period, it is to
your advantage to get caught up as soon as possible.
Laboratory Reports:
Reports which are late will be assessed a 20% penalty for each period beyond the due date.
Reports: A report for each laboratory experiment will be due one week after the scheduled
completion date of the experiment. The title of the experiment, what analyte was determined, the
mean value of the analyte, the standard deviation, calculated confidence limits (all the required
information may be found in a single spreadsheet and associated graphs). The original
observations from your laboratory notebook, any computer generated data tables, graphs, and
calculations will also be included as attachments.
Each laboratory period:
I will assume that you have read the appropriate material in the laboratory text prior to the laboratory
discussion session. A very brief discussion of the theory behind the experiment will be presented.
Included in the brief discussion of the individual experiment will be any modifications to the procedure.
Initially we will design and generate MS Excel spreadsheets together, but as the semester progresses, I will
expect you to take on more of the responsibility of the design and generation of your own MS Excel
spreadsheets.
All experimental data must be entered in ink into your carbonless laboratory notebook with
numbered pages.
Laboratory reports are to be turned in to the front of the box labeled CHEM 5, which is available
in Room 607, prior to the beginning of laboratory on the due date. All reports submitted after the
beginning of laboratory on a scheduled due date will be considered late and will incur the late penalties.
Unauthorized Experiments are forbidden. Since you can endanger not only yourself but others as well,
any violation of this rule constitutes grounds for immediate dismissal from the course. A laboratory
schedule is included as an addendum.

Extra Credit Options:
Students always ask if there is some extra credit that they can perform. The following extra credit option is
available,but remember the word extra implies extra work must be done to receive the credit.
As you can see from the laboratory schedule there are a significant number of experiments that we will be
performing this semester. However, if you are exceptionally efficient during the semester there is sufficient
time and experiments available for you to do one or two extra experiments to obtain extra credit.
Academic Honesty:
You are expected to comply with the student responsibility rules written in the second edition of the
Student Rights and Responsibility Handbook, entitled, “Working Together Toward Positive Solutions.”
This handbook is, to the best of my knowledge, available at the office of the Vice President of Student
Services.
Students with Disabilities:
I encourage students with disabilities, including “invisible” disabilities such as chronic diseases, learning,
and psychological disabilities, to explain their needs and appropriate accommodations to me during my
office hour. Please bring a verification of your disability from the Learning Skills or DSP&S Offices and
counselor or specialist’s recommendations for accommodating your needs. DSP&S are located at Room
810.
Very Important Note:
All students who enrolled in Chemistry 5 have taken a positive step to enroll. This to me means we
have a contract between us, you will attend class on time regularly and I will commence classes on
time and will conduct a class that is designed to help you understand the concepts presented in this
chemistry class.
If for any reason you want to break this contract, you (the student) must make and take a positive
step to remove yourself from the roll sheet prior to the last day to drop the class. If you do not then
the grade recorded on the final day of the semester will be the grade for the semester.
Stated more bluntly:
Dropping Policy:
Dropping this course is your responsibility. Do not expect me to drop you from this course! If
you quit showing up, I will keep giving zero scores to your missed activities/quizzes, exams, and
laboratory reports that will ultimately result in an F. Please drop the course yourself.

Analytical Problem Solving: Use of the Analytical Literature: (50 pts)
The point has been made that analytical chemistry is not so much performing analysis as it is solving
chemical problems. First comes knowledge and practical experience with the techniques of sample
preparation, separations and measurements. Second is the accumulated knowledge inherited from
predecessors, who have worked on similar problems
Therefore, to integrate the two areas, a literature search will be performed to solve one problem selected by
each student. You may select a problem from the list attached to the Analytical Search Document or
purpose your own problem to solve (this is the preferred option).
