4/11	Today I distributed an assignment that will serve as our homework for the topics of separations and spectroscopy. The assignment is worth 100 points and may be completed with a partner. Due dates and details are in the file.
3/27	I will be gone from campus on Friday, April 4. On Monday, March 31, I will distribute Exam 5, Part III to you and invite you to use the time on April 4 to work on it...I can dream, can't I?
3/27	For the Lead in Paint lab, it is useful to do dilutions by mass and possible serial dilution. I've put together this brief summary of the thought process and mechanics behind these concepts that may help as you prepare for lab.
2/27	On Friday, Feb 29, I will distribute Exam 2 as a take-home exercise. It will be closed note, closed book, and closed other person. You will have a time limit for the exam (~2 hours), but can take the exam at any time, as long as it is turned in by 4:00 PM on Friday March 7. I will be around all day on March 7, but we will not have class that day. I will be in our classroom between 8:00 and 9:25 AM if you wish to sit in the rook at that time. The exam will cover Calibration (Ch. 5), General Equilibrium Concepts (Ch. 6), Activities (Ch. 8), and Systematic Equililibrium (simultaneous equilibria) (Ch. 8).
2/18	Titration curve data is available at: U:\_SC Student File Area\CHEM 222\CHEM 222 Titration Curves These text files can be opened in Excel and should produce two columns of date (pH, Volume).
2/8	These guidelines for determining the pK_a of a weak acid from a titration curve should help as you analyze your data for the K_a lab.
1/9	Lab WILL MEET during the first week of class. We will begin with the "Introduction to the Analytical Balance and Volumetric Glassware" and "Spreadsheets and Laboratory Data Analysis" exercises.
1/4	A draft of the Spring 2008 Syllabus is available by clicking on the "Syllabus" link at the left. A final version will be distributed the first day of class.
12/17	Review Objectives for Quantitative Analysis: Truman Faculty have compiled this list concepts that should be somewhat familiar at the beginning of the semester. Most, if not all of these topics should have been covered in a General Chemistry course. Don't panic, you do not have to be an expert with each concept, but if you come across something that you have NEVER seen before, you may want to take a look back at your Gen. Chem. text to refresh your memory.
12/17	Textbook shoppers: The text for the course is "Quantitative Chemical Analysis", 7th edition, by Daniel C. Harris, published by W.H. Freeman.
