CHM 113 & 117 Fall 2014
"A teacher is never a giver of truth - he is a guide, a pointer to the truth that each student must find for himself. A good teacher is merely a catalyst". Bruce Lee
Please check this page each week for updates and announcements.
Refer to lab schedule tab and plan your experiment in advance.
All students should attend assigned lab each week. If you fail to attend one of the listed experiments in your schedule you cannot pass this course.
All students should prepare in advance for each lab experiment. In addition to lab manual, learning materials will be posted in LIVE D2L (use your Wilkes username and password, select CHM 113 D1 x 117 D1 course). Your progress will be monitored and evaluated. If you cannot find the course (CHM 113 D1 x 117 D1) in LIVE D2L, it means that you are not registered for the Disscussion (CHM 113 D1 or CHM 117 D1).

Thursday, October 23: The 8th Learning Session (Qualitative Analysis of Cations) has been posted in LIVE D2L.
Wednesday, October 22: There will be a rotation of labs during the weeks of November 3-7 and November 10-14. Check the schedule tab and click on Molecular Modeling - Spartan to check when you are scheduled to do the Spartan lab. Plan your lab preparations in advance.
If you are scheduled to perform the Spartan lab during the first week of November, prepare in advance (using a library computer) and go to the assigned BREIS computer lab according to lab schedule. If you are scheduled to perform the Spartan lab during the second week of November, you are going to perform the Fuel in a Bic Lighter lab before the Spartan lab. Before the lab rotation, you are going to do the Qualitative Analysis of Cations lab as scheduled.
Sunday, October 19: The report form for the Examination of the Hydrogen Spectrum has been posted. Check the Report Forms tab.
Thursday, October 16: The 7th Learning Session (Examination of the Hydrogen Spectrum) has been posted in LIVE D2L.
Sunday, October 12: The report form for the Determining Ascorbic Acid Content in Vitamin C Tablets has been posted. Check the Report Forms tab.
Wednesday, October 8: The 6th Learning Session (Determining the Ascorbic Acid Content in Vitamin C Tablets) has been posted in LIVE D2L. There is an example on how to calculate the Vitamin C content using one set of experimental data.
Monday, Sept 29: The report form for the Synthesis of an Iron Coordination Complex has been posted. Check the Report Forms tab.
Thursday, Sept 25: The 5th Learning Session (Preparing an Iron Coordination Complex) has been posted in LIVE D2L.
Monday, Sept 22: The report form for the Physiologically Important Anions has been posted. Check the Report Forms tab.
Thursday, Sept 18: The 4th Learning Session (Physiologically Important Anions) has been posted in LIVE D2L.
Thursday, Sept 11: The 3rd Learning Session (Gravimetric Determination of Phosphorus in Plant Food) has been posted in LIVE D2L. It is very important that you review the session (it's a short one). In order to apply the Green Chemistry Principles, all quantities were scaled down. Please use the smaller quantities specified in the online Discussion. This is not a change in the procedure; it only encourages you to think before acting. Finding ways to reduce the chemical waste without compromising the analysis/result represents an important step toward improving the world around you.
Sunday, Sept 7: The report form for the Separation of a Ternary Mixture has been posted. Check the Report Forms tab. Please do not use the form to record data during the lab.
Wednesday, Sept 3: The 2nd Learning Session (Separation of a Ternary Mixture) has been posted in LIVE D2L. There are few examples on how to calculate uncertainties. Since you need this knowledge for density calculation in the first lab report, you may want review this session before completing the lab report for Analytical Weighing. ..
Monday, Sept 1: The report form for Analytical Weighing .... has been posted. Check the Report Forms tab. Please do not use the form to record data during the lab.
Thursday, Aug 28: It seems that LIVE D2L access issue has been resolved. Please complete all steps in the online session.
Wednesday, Aug 27: As I promised, the 1st Learning Session has been posted in LIVE. However, there are IT issues and only half of the students can see CHM 113 D1 x 117 D1 in LIVE. The Wilkes IT Department will solve this issue by the end of the day. Please be patient.
This is the schedule of lab experiments. If there will be changes, the schedule will be adjusted to reflect those changes.
If you are scheduled to perform the Spartan lab during the first week of November, prepare in advance (using a library computer) and go to the BREIS computer lab according to lab schedule. If you are scheduled to perform the Spartan lab during the second week of November, you are going to perform the Fuel in a Bic Lighter lab before the Spartan lab.
Note the rotation of labs during the weeks of November 3-7 and November 10-14. Click on Molecular Modeling - Spartan to check your schedule. Plan your lab preparations in advance.
