Prerequisite: CHE112

Course Goal: To offer material which will enhance the student's appreciation and understanding of chemistry as a quantitative science.

Course Objective: This course introduces students to the techniques and theory of gravimetric, volumetric, iodometric and visible absorption spectroscopic analyses. Its entire focus is on quantitative applications to chemical analysis.

Course Requirements:

Required Texts and Other Materials

Lecture

"Topics in Quantitative Analysis, 2007 Edition"

This text and the laboratory manual listed below may be purchased in the bookstore or downloaded at no charge from the link at the web site

http://www.csudh.edu/oliver/oliver.htm

The advantage of purchasing it is that the student doesn't waste a lot of time printing out the Web version. The disadvantages are that (1) its cost is around $11, (2) Web links to color photos are only described and not included. The student should do what seems to be the most efficacious for success in the course.

Laboratory

The following items are required for the laboratory part of the course:

1) The lecture text

2) The "Chemistry 230 Lab Manual, Fall, 2007 Edition"

3) A laboratory notebook which must be a quadrille ruled 10" x 7-3/4" composition notebook.

A spiral bound, 3-ring or notebook with double pages for copies is unacceptable

4) Laboratory safety glasses.

All of these items can be purchased in the University Bookstore.

Problem sets

A list of suggested problems taken from the collections at the end of the chapters in the textbook we formerly used in CHE230 by Skoog, West and Holler (SWH) is given below. Those problems will be xeroxed and distributed in class. Working these problems is not mandatory and no work needs to be turned in, however doing these problems in a regular and systematic manner is crucial to success in this course. Moreover, the student is encouraged to work other problems dealing with subject matter found to be of particular subtlety or difficulty. My experience has been and continues to be that the more problems worked the better prepared is the student to do well on the examinations. Answers to these problems are available from the Solutions Manual to that textbook. Copies of this Solutions Manual are available in the laboratory, NSM C-315, and the Reserve Book Room of the University Library.

World Wide Web Exercises

I find that many students in Quantitative Analysis need some review on solving freshman chemistry problems. To that end, problems from Chapter 2 of the book formerly used as a text in this course have been included in the list above. Another way to improve your freshman chemistry problem solving skills is to visit one of our several computer laboratories and connect to the CSUDH Chemistry Web page. There you will find a link to chemistry problems:

http://proton.csudh.edu then link to "Homework Pages"

The nearest computer lab is in NSM D-331, open 8-5 Monday through Friday.

Any of the exercise categories on the subjects of mass, volume, density, moles, molarity, balancing equations, percent yield, limiting reagents, pH, oxidation reduction equations and nomenclature are categories you ought to consider investigating to determine if you have deficiencies in those areas. Specific instructions on using the Web will be distributed soon after the beginning of the semester. I guarantee that if you have demonstrable skills in these areas, your performance on examinations will be satisfactory.

Attendance: All activities in class and lab are connected with the learning process in Quantitative Analysis. My experience has been and continues to be that there is a direct connection between a student's attendance and participation in classroom and lab activities and his or her academic success.

Schedule of Examinations and Experiments

During the fifteen weeks of instruction three 100-point examinations will be given. A 150-point examination will be given during the final exam period. Scheduled dates for these exams, together with the chapters that these exams will cover, are shown below. The final exam will consist of questions drawn from all the material that was presented during the course. The first exam will have questions taken from the Web site. All other exams will include material consistent with that covered in class, but which is related also to work done in laboratory.

Policy on Missed Examinations:

Hour Examinations: A student who notifies the instructor prior to the examination of his/her inability to take the examination and who can give acceptable and verifiable reasons for this inability, will be given a score, for the missed examination, that represents the average of the other two, among the first three, examinations. A student who misses an examination for no valid reason, or misses a second one, will receive no points for that examination. Under no circumstance will make-up examinations be given.

Final Examination: A student who misses the final examination for reasons beyond his/her control will receive an Incomplete (I) grade for the course. The final examination will have to be made up before a course grade can be assigned.

Experiments

Each experiment will be worth 100 points. You will be graded on your accuracy, precision and the skills required to be a competent laboratory technician.

Due Dates:

During the semester you will carry out five analyses:

In addition to these analyses you are also required to do the "Heating Crucibles to Constant Weight" and the "Calibration of a Buret" exercises. These exercises are to be done in preparation for performing the first and second experiments, respectively.

All experimental results and the laboratory notebook are due by 4:00 p.m. on Thursday, December 6.

Make-up Policy: Our experience has been that each experiment can be easily completed in the time allotted. There has never been an occasion when a student needed to make up work outside laboratory hours. Requests for such special scheduling have been refused and as the semester progressed the students involved were able to catch up with their peers. Regular laboratory attendance is mandatory. If you foresee a major problem with your laboratory attendance you must keep in close contact with the professor so as not to miss the applicable "drop" deadline.

Grading Policy

Even though the course has both a lecture and laboratory component, only one composite grade will be assigned for the course. This composite grade will be based on the total number of points, both lecture and laboratory, earned in the course. The maximum number of points that can be earned is 1000. Completion of all the laboratory work is one of the requirements for a passing grade in the course. On page four of this syllabus is a table which indicates the course grade you can expect for a given course point total.

Statement on Academic Integrity and Plagiarism

Academic Integrity is described and discussed and Plagiarism is defined and discussed in the University Catalog. This course will be taught in a manner which upholds and enforces those statements.

Disabled students will be accommodated in accordance with University policy to the extent possible for a laboratory course. Please see the University Catalog for details.
