Good attendance is essential to successful mastery of course material.  Attendance will be monitored by weeky quizzes.  Please notify the instructor of excused absences.  These are described in the current University Catalog and in the TSU Student Handbook.
Grades will not be lowered due to poor attendance.  However, good attendance may be considered as a bonus point for borderline grades at the end of the semester.

University Policy:

The student is expected to be familiar with student responsibilities as outlined in the current University Catalog and TSU Student Handbook.
The departmental Academic Honesty Policy can be found in the Freshman Chemistry Laboratory Manuals.
Students with documented disabilities may request accommodations that will enable them to participate in and benefit from educational programs and activities.  To ensure that services will be available in an efficient and timely manner, students with disabilities are strongly encouraged to contact Student Disability Services, Math Bldg. Suite 201, (254)968-9400.

Make-up exams will be by permission of the instructor.  Please contact the instructor immediately after the missed exam to make arrangements.  There is no make-up for quizzes.

Course Objectives:

Upon completion of this course, the student will be able to demonstrate a satisfactory understanding of:

1.    Accuracy, precision, and data handling techniques..
2.    Stoichiometric calculations.

3.    Basic principles of chemical equilibrium and be able to write equilibrium constant                        expressions for chemical reactions.
4.   The chemical natures of acids and bases and be able to calculate pH of solutions of strong            and weak acids and bases, salts, and buffer solutions.
5.   Factors affecting solubility equilibria and be able to calculate solubilities.
6.   Electron exchange in chemical reactions, the basic principles of electrochemistry, and be able       to balance oxidation / reduction equations.
7.   Gravimetric Analysis.

Sources of Assistance:

1.   The textbook.  It cost a lot of money.  Read it and work the homework problems.  Solutions          to many of these problems are in the back of the book.
2.   Your instructor.  If you are having difficulty working the problems, call or come by to see            me.  However, it is not recommended that you do this the hour before class.
3.   Your classmates.  I do not mind if students work together on homework problems, as long as
this is not abused.  However, do not get into a situation of "the blind leading the blind."  If in
doubt, refer to #2 above.
4.   Other Chemistry texts available in Room 434 and the library.
5.   Tutors.  Many upper level Chemistry majors tutor (for money).  A list will be available in the
departmental office in Room 117.

Course Schedule:
see attached.


note:  The course schedule is tentative.  The instructor reserves the right to change this syllabus at any time.  Any changes will be announced in class in advance.

Quantitative Analysis - Laboratory Policies


Lab Manual:

There is not a separate laboratory manual for this course; the experimental procedures are in the back of the textbook. 

Lab Notebook:

Each student will be responsible for purchasing a Lab Notebook with numbered, duplicate pages, and a handwritten outline, or summary, of the steps to be taken during each experiment will be recorded in the notebook.  These procedures will normally be reviewed in class prior to the date that the analysis is performed.  No unknowns will be issued until this outline has been reviewed by the instructor.  A copy of this outline will be handed in with the lab report.  All data obtained will also be recorded in the lab notebook, and the instructor may examine the notebook at any time.  A well-kept notebook may be the basis for bonus points on the lab grade.

Lab Reports:

A formal, written lab report is required for each laboratory exercise (10/semester).  Lab reports will be scored based upon the following rubric.

Grading Rubric for Lab Reports


Component / %


Basis of Evaluation


Organization / 10%

The report should be in the standard format of Introduction, Theory, Experimental, Results/Conclusions, References


Mechanics of Writing / 10%

The report should be written using correct sentence structure and free of errors in grammar, spelling, and punctuation


Content / 60%

The report must clearly describe the theory of the determination, including all relevant chemical reactions, equations, and any other major factors which would affect the analysis. 


References / 20%

The report must include at least 5 relevant references from legitimate sources and references must be listed in a recognized scientific format.  All references must be cited in the body of the report at the point where the referenced material is presented.


Other factors

Points will be deducted for lateness at a rate of 10 points/week.  Reports will not be accepted after 2 weeks.  Plagiarism will result in a grade of 0 on the report and may result in other sanctions appropriate to the severity of the offence.

Chemistry 307 lab reports are due on the dates indicated on the course schedule.  Late reports will be penalized at the rate of 1 letter grade per week.  For example:  If a report is due on Monday and would have received a grade of B, on Wednesday it would receive a grade of B-, on Friday it would receive a grade of C+, on the next Monday it would receive a grade of C, etc.  No reports will be accepted after a two week period has elapsed.  (This policy does not apply to numerical results).
Reports should be handed in (in duplicate) in an 8 x 10 manila folder.  The reports should consist of the following components.

1.  Introduction:

This is a brief summary of the purpose of the experiment and the basic analytical principles involved.

2.  Theoretical Discussion:

This is the bulk of the report.  The theoretical discussion should cover the specific theory of the determination, including all relevant chemical reactions and equations, and include such factors as function of particular reagents, method errors and means of offsetting them, impurities, formation of precipitates, detection of endpoints, blanks, indicators, pH requirements, temperature, and any other factors which would affect the analysis.  The student is expected to use various reference books, the textbook for the course and other textbooks, and original research articles to obtain this information, and these sources must be acknowledged in the report.  Each report must contain at least five different references and at least three original references should be utilized during the course of the semester.  The original references may not be from online sources, and must be accompanied by a short summary of the article on a separate sheet of paper.

3.  Experimental:

This will be the duplicate experimental procedure outline from your lab notebook.

4.  Numerical Results:

These results should include the results for three individual samples, the mean result of the three samples, and the average deviation.  If one result can be discarded on the basis of a Q-test, this fact should be reported on the result sheet and this result may be omitted from the calculation of the mean.  The actual calculation for at least one sample should be shown, and the duplicate data sheet from the lab notebook should accompany the report.

The numerical results will be graded separately from the theoretical discussion report.  The numerical grade will be based upon the following:

            Difference between reported and true value                               Grade

                                    0.00 - 0.1 %                                                    10
0.11 - 0.2 %                                                       9
0.21 - 0.35 %                                                     8
0.36 - 0.5 %                                                       7
0.51 - 1.0 %                                                       6
more than 1.0 %                                                  5

Each of the three individual sample results is worth 10 points, and the mean is also worth 10 points.  The precision grade will be based on 10 points also, with one point deducted for each one per cent of relative average deviation.  Therefore, each analysis has a total value of 50 points.

5.  References:

References should be in the following format:


Willard, H.H., Merritt, L.L., and Dean, J.A., Instrumental Methods of Analysis, 4th ed, Van Nostrand, Princeton, N.J., 1965, pp. 74-78.


Patton, J., and Reeder, W., "New Indicator for Titration of Calcium with (Ethylenedinitrilo)-tetraacetate," Analytical Chemistry, 28, 1026 (1956).
