Remember that this week in lab you will be doing your second analysis.  Next week you will be presenting your results to the group.  If you don't have a copy of the expectations for the presentation, I will have copies available in lecture.

A note on the electrochemistry problems that I handed out in class; the second and third pages are in reversed order.

Next week's schedule is as follows: Monday, no class; Tuesday, class as usual; Wednesday, review sessions during the first hour of the lab times (go to your regular lab, if possible); Thursday, no class and finally Friday's class will be in Baldwin 349.

The class results for the ferric oxalate titrations are posted on the class laboratory page.  Click here to obtain the results.

Please e-mail me your results (% by mass oxalate and % by mass Fe) for last week's laboratory.  I will post these tomorrow.

There is no pre-lab for next week's exercise.  I will hand out the lab packet in lab and then we will discuss it and you will write the procedure in lab.

Next week's review questions are 3-92, 8-100, 9-62, 10-66 and 15-74.

Lab this week is Molecular Models 1.  We have already completed the Lewis dot structure part and will do the VSEPR part on Monday.  You do not need to write anything in your laboratory notebook for this lab.  The sheets that I handed out are the main part of this exercise and additional copies are available on the Molecular Models 1 page. There is also a sheet of questions to answer once we have finished the exercise.  I may also be talking about organic chemistry in lab so that we can finish parts F and G.

Don't forget to have your write-up for the Qualitative Analysis exercise ready for Wednesday, even if you did not complete all the analyses.

Remember that there is no laboratory Wednesday because of the University Conference.  Please try to attend this important event and learn more about how the University is run and its plans for the future.  Nothing will be due for the Qualitative Analysis exercise until next week.  Also, next week we will be working on the Molecular Models I exercise.

Lab next week is the first week (cations) of the Qualitative Analysis exercise.  Please review equilibrium (chapter 8 especially).  Don't forget there is a pre-laboratory exercise due at the start of lab on Wednesday (create a flow chart for the chloride group of cations).  Also don't forget to prepare your notebook with a Statement of Purpose and a Procedure.  For the Procedure you can simply tape or paste in the flow charts from the web page into your notebook (on both the original and duplicate pages).  You will receive a copy of the chloride group separation scheme, with the actual amounts to use, in lab after you turn in your flow chart.
