CHEMISTRY 3452

Quantitative Analysis Lab

 

 

This 1-hour lab course is to accompany the CHEM 3451-001 Quantitative Analysis course to cultivate students' hand-on operation skills in field of quantitative analysis. Various experiments are designed to utilize statistical treatment of data, sampling and transfer techniques, gravimetric and volumetric methods, titration analysis, electroanalytical and introductory instrumental analysis.

 

CHEM 3452 will meet in Masters Hall Room 304.  Refer to your schedule for your laboratory time.

 

Instructor                    Dr. Faith Yarberry,                Voice:(940) 369-7615,

Faithyarberry@yahoo.com            Masters Hall Room 16

                                    (Please begin all email subject lines with Quant: so that I will make

                                    sure to pay immediate attention to the email)

 

Office Hour                Tuesday and Thursday from 11AM- Noon in Masters Hall Room 16,

                                    (Please call or E-mail me if you have questions or need a time other

than that listed).

 

 

Lab Manual              The Lab Manual will be provided. There will be a brief discussion of each lab at the beginning of the period.  Each student will be expected to have read the lab manual before coming to class, since the discussion will focus on why, not how, the lab is done.

 

 

 

Additional Materials

 

You will be required to maintain a laboratory notebook in which all information, data, and observations are entered using a black or blue ink pen. Notebooks will be inspected at unannounced times during the semester, and graded according to completeness and organization. Eye protection, in the form of either safety glasses or goggles, is mandatory!! The "TA Evaluation" portion of your lab grade will reflect your attitude, preparedness, and safety-consciousness during lab.

 

Lab Reports

 

The last page of each lab handout is the lab report sheet, on which you will report your lab results.  This information will come directly from your lab notebook (see below), and any blanks on the report must be filled in or explained.  The report sheets are due at the beginning of the lab period immediately following the completion of the lab.  Ten points will be automatically deducted from late lab reports, and no lab will be accepted more than two weeks after the date due.

 

Lab Notebook

 

All students will use a lab notebook to record all data obtained in this lab.  The notebook must be one in which the pages are permanently attached -- loose leaf notebooks are not acceptable.  Recording data on scratch paper, paper towels, etc. before transfer to the notebook is expressly forbidden.  Any student found using such scratch paper will have 10 points automatically deducted from their lab grade for that lab and the scratch paper will be discarded.

 

Grading

 

The lab grade will be calculated as follows:

 

            laboratory reports                                     70%

            laboratory notebook                                               5%

            2 Quizzes                                                         20%

            TA Evaluation                                                   5%

 

Notebooks will be inspected at unannounced times during the semester, and graded according to completeness and organization. The "TA Evaluation" portion of your lab grade will reflect your attitude, preparedness, and safety-consciousness during lab.

 

Grading Scale  

 

 

Final percent Average                                                               Letter Grade

 

            90 - 100 %                                                                              A
