5/4 Oral Presentation of one Experiment. (If presentation is last experiment, you can submit ppt file in place of written report) Presentation Material (ppts) due following presentation

V. Total:  5 two-week experiments + 1 thermo/Computational Chem + 3 Preliminary Experiments

VI.  Reports:

• Preliminary Experiments (i), (ii), (iii), All individual reports (Informal Reports)

• Experiments 1-14, Reports by Group (Formal Reports Per “Lab Report Info” on Moodle)

• Experiment 15, Individual Reports (Informal Reports)

• Oral Presentation, By Group. 

The following is the syllabus for Chem 339 for Fall 2010.

Chem 235 students (there were none in Fall 2010) would not have done experiments 12 and 13, as those students have already completed those experiments in the Analytical Chemistry Laboratory course.  Chem 235 students instead, perform two additional PChem Experiments (Labs Number 1-11) in place of experiments 12 and 13.

Summary:

Chem 339 schedule

Preliminary Experiments i), ii), iii)

Experiments 12 and 13

Three experiments selected from Experiments 1-11

Experiment 15

Oral Presentation

Chem 235 Schedule

Preliminary Experiments i), ii), iii)

Five experiments selected from Experiments 1-11

Experiment 15

Oral Presentation

Selection of experiments is determined by availability of equipment and is at the discretion of the Instructor.
