Text: "Experiments in Physical Chemistry,
Attendance is compulsory. Depending on enrollment, the class is subdivided into groups of two or three students ("partners") who work together on the same experiments during the whole semester.
Experiments are assigned one week in advance. Before starting a new experiment, (i) the written report on the preceding experiment must be turned in, and (ii) you and your partner(s) must pass a qualifying oral test in the lab at the beginning of the lab period. You are required to know, in detail, how to carry out the experiment, the principles of the apparatus you will be using, and the basic theory and equations you will apply in calculating the results.
Before starting an experiment you will have to clean the equipment, if necessary, and take inventory.
The measurements should be performed carefully and safely. Meticulous notes of the primary data obtained should be kept in a notebook, individually by each partner.
After finishing an experiment, you must clean all equipment (including glassware) and hand them over to the TA who will check their condition and the inventory. Each student is responsible for the equipment he/she is using. Breakage of equipment should be reported immediately to the instructor.
The part of an experiment involving calculation, organization, and interpretation of the results must be the work of each individual student without the collaboration between partners, and must show his/her understanding and competency. Violation of this rule may result in a zero score for the report. The format of this part of an experiment is the lab-report. A report should consist of four sections:
1) Introduction (ca. ˝ page) Brief description of the purpose of the experiment; include a schematic drawing of the apparatus or circuit used. Specify the chemical system investigated.
2) Experimental Presentation of the primary data in a logical sequence, taken from the notebook. They must be reorganized and tabulated or plotted, if applicable. Specify what was measured (e.g., time, temperature, etc.).
3) Calculations and results Presentation of the equations used. Also, include the most important steps of your numerical calculations, and the computer program used. Pay great attention to units and to significant figures. The final result(s) should be reported as "<X> ± s unit," and marked conspicuously. Cite the source of numerical values of quantities if you took them from the literature (author, title, publisher, place, date, page).
4) Uncertainties in the results Analysis of errors in the measured and derived data. Show quantitatively how the uncertainties of your primary data effect the final results. Compare your results with accepted values taken from the literature, and show the relative error.
Grades will be determined based on the following criteria:
a) your understanding of the subject reflected by the organization, analysis, and presentation of the results in your reports;
b) the accuracy of your measurements and results;
c) the number of experiments you have carried out during the semester;
d) the neatness of your reports;
e) your competency demonstrated on the oral tests;
f) the quality of your cleaning up after each experiment.
Safety Regulations The wearing of safety glasses is mandatory in the lab, and no eating or drinking is allowed. On general safety precautions read Appendix C of the text. The laboratory is equipped with fire extinguishers. Memorize the locations of the emergency shower and eye washer in the lab. First aid kit and telephone for emergency cases are available in the Storeroom (1st Floor, CPB). Any accidents should be reported immediately to the instructor. Waste chemicals must be collected in designated containers for proper disposal by the Environmental Health and Safety Office.
Lab Attire: READ
THIS INFORMATION VERY CAREFULLY!!!
Goggles, gloves, and aprons are provided and are required at all times.
Online Safety Training:
Disabilities If you require an accommodation based on disability, I would like to meet with you in the privacy of my office the first week of the semester to be sure you are appropriately accommodated. It is the responsibility of the student to inform faculty and provide authorized documentation obtained through designated administrative channels.
Drop for Non-Payment of Tuition If you are dropped from this class for non-payment of tuition, you may secure an Enrollment Loan through the Bursar's Office. You may not continue to attend class until your Enrollment Loan has been applied to outstanding tuition fees.
Grade Replacement Students enrolling in a course with the intention of replacing a previous grade earned in the same course must declare their intention to do so at the Registrar's Office by Census Date of the semester in which they are enrolled.
Pass/Fail If P or F is a grade option in this class and you intend to take this class for a pass/fail grade instead of a letter grade, you MUST inform the instructor, through the necessary paperwork, of your intentions BEFORE the census date.
Academic Dishonesty All students are expected to pursue their scholastic careers with honesty and integrity, and the Department of Chemistry and Biochemistry will not tolerate academic dishonesty in any form. "Scholastic dishonesty includes but is not limited to cheating, the submission for credit of any work or materials that are attributable in whole or in part to another person, taking an examination for another person, any act designed to give unfair advantage to a student or the attempt to commit such acts." (Regents Rules and Regulations, Part One, Chapter VI, Section 3, subsection 3.2, Subdivision 3.22.)
Bomb Threats In the event of a bomb threat to a specific facility, University Police will evaluate the threat. If required, exams may be moved to an alternate location, but exams will not be postponed. UT-Arlington will prosecute those phoning in false bomb threats to the fullest extent of the law.
