Textbook: Quantitative
Chemical Analysis, 8th Edition, by Daniel C.
Harris, Two copies of the text will be on reserve at the library. Chem 254
Lab Experiments will be distributed by email through your TA. Also see UC Davis ChemWiki for additional reading material.
Electronic Device Policy: If you choose to use a laptop, tablet or similar electronic
device, you will be required to sit in the back of the lecture hall so as not
to create a distraction for other students. Phones are to be turned off.
Texting will not be allowed, if you are caught texting in my lectures you will
be asked to leave. TEXT ENTRY CALCULATORS WILL NOT BE PERMITTED FOR USE ON
EXAMS.

4 Executive Summary.
Introduction: This course
serves these primary purposes.
1. To expand your knowledge of aqueous equilibria and to apply it to the determination of
analytes in several types of samples. The concepts of chemical equilibria are
important to the biological, geological, and environmental sciences and
chemical engineering. In some cases examples will be presented that discuss
these applications.
2. To introduce you to methods and techniques of obtaining very
accurate determinations of materials
by three different approaches: volumetric, gravimetric and spectrophotometric
analyses. Learning to work quantitatively is a necessary skill for all
scientists. This
3. To help you develop as an independent learner and thinker. As you leave the university, your progress as
a professional will depend on your ability to keep up will advancements in your
field. In most cases you will have to learn these new concepts on your own. You
will find that most the amount learning you have accomplished in a lifetime is
done post-graduation. A university education is therefore should not be a
narrow vocational track, but an experience that teaches you how to appreciate
and acquire new knowledge, ideas, and concepts on your own. Key points for
success in the course:
It is
strongly suggested that you work on homework problems on a daily basis. This is important since the questions asked
of you on the exams will not only test recall of knowledge but your reasoning
abilities. Those abilities can only be developed by you with the homework
problems.
Listening to
lectures alone will NOT develop problem solving/reasoning abilities. Working at a steady pace is important since the
material takes time to assimilate. Attendance of lecture is required.
Attempting
to “cram” Chem 253 material a few days before the exam will lead to disaster.
Read your
textbook on a regular basis. Also, if you
have missed, are deficient, and/or forgotten material from Chem 111/112 in many
cases you be expected to learn this material on your own. Also you may see me
or the TA’s for help.
Spend 1-3
hours of study time per lecture hours. If you are rusty in algebra or have had Chem 112 more than two
years ago you may find the need to spend more than three hours per lecture
studying for this course.
Ask
questions and participate in lecture. Learning is
not a passive experience. You must get over the feeling of intimidation when
you must ask a question. This is important for your development as a
professional. In many cases I will call on you in lecture for your input on
topics and to answer questions. Names will be selected at random.
Expect to
have work through problems if you seek help. This is to help you develop your reasoning abilities. Passively
watching the TA’s or myself will not help you problem-solving skills. Also,
because of the time constraints, please note that neither the TA’s nor I may be
able to troubleshoot the algebraic steps you may have chosen for a particular
problem. Alternative and simpler routes may be offered instead.
Exams and Grading Policy There will be three mid-term
examinations and a nationally standardized, American Chemical Society (ACS)
comprehensive final.
Three 50 minute
exams, Exam 1 – September 14th, 2016, Exam 2 – October 12th,
Exam 3 – November 30th
All mid-term
exams will be given in normal lecture periods. Your final grade will calculated
in the following way:
Excluding
the ACS Final the grades
will be assigned as follows: A: 100-82%, B: 81-67%, C: 66-57% D: 56-45%, F:
less than 45%
Including
the ACS Final the grades
will be assigned as follows:
A: 100-78%,
B: 77-65%, C: 64-50%, D: 49-40%, F: less than 39%
ACS Final
Challenge. If you score greater than 80% percentile your grade will be an A
regardless of your previous performance.
Grading Scheme, 3x50 min exams = 60%, ACS Final Exam = 30%, Online Homework = 10%. In the
case of an excused absence of one of the 50 min exams the following
applies: 2x50 min exams = 50%, ACS Final = 40%, Online Homework = 10%
50 min Exam Make-up policy. In the case of an acceptable University of Idaho excused absence*,
the weight of the other mid-terms and final exam will increase.
*An excused absence is defined by University of
Idaho policy as a) an approved field trip or other official UI activity; b)
confinement under doctor's orders; c) call to military duty; or d) leave of
absence granted by student's academic dean.
Missed Lecture(s) Attendance is not mandatory but recommended. I do not provide lecture
materials to students who have missed or cut lectures.
Expectations for Student Conduct in Lectures. I expect a
professional atmosphere where you will not be distracted by electronics,
reading materials or conversations. This will be expected of you in a
professional environment where you will pay attention regardless of boredom and
deliver ideas to your boss and colleagues. See MIT Prof. Sadoway’s
expectations at youtube especially at 26:47.
Reasonable Accommodations Reasonable
accommodations are available for students who have a documented disability.
Please notify the instructor during the first week of class of any
accommodation(s) needed for the course. Late notification may mean that
requested accommodations might not be available. All accommodations must
be approved through Disability Support Services located in the Idaho Commons
Building, Rm. 333.
Calculator An
inexpensive calculator is required. You will need the calculator during labs
and exams. It should have the capability for logarithms, exponentiation
(antilogarithms), yx and
scientific notation operations. TEXT ENTRY CALCULATORS WILL NOT BE PERMITTED
FOR USE ON EXAMS.
Homework Assignments -- To be revised throughout this semester.

from the Registrar’s office.
Notes regarding the ACS Final.
This final counts as 33.3% of your total grade. The reminder is determined by
your hour exams. There is no
study guide coming from the ACS on this topic. All test takers – nationwide
have the same disadvantage so that’s reflected in the percentile
distribution. For review I suggest going over all your old hour exams and
homework problems sets and notes. Also your textbook provide exercises at the
end of each chapter. These exercises are solved for you starting on page S1. So
if you are looking for more material I would suggest the exercises from
Chapters 1- 4, 6, 8 (except K), 9, 10,
11, 12A, 12B, 13, 14, 15, 16 (except G), 17, 23A.
