Chapter 3 - Example 3.1, 3.3
Chapter 4 - Example 4.7, 4.12
Chapter 6 - Example 6.1 - 6.4, 6.10, 6.11, 6.12, 6.13
Chapter 5 - Example 5.5 - 5.9, 5.20, 5.23, 5.25
Chapter 7 - Example 7.1, 7.2, 7.4, 7.5
Chapter 8 - Example 8.1 - 8.6, 8.9, 8.10 (Test 1 after completion)

New practice problems have been assigned:

Chapter 11 - Example 11.1 - 11. 9, 11.11, 11.15 - 11.17, Problems 23, 25, 31, 51, 59, 75, 77, 125 (Test 2 after completion)

2. CLAB 124-------Please be prepared for experiment 7. Please print and bring to class the modified procedure that is a link on the Information Sheet (Link to 124 experiment Buffers). You should read the introductory material and the procedure in your lab manual (or modification if applicable). Be sure to prepare an outline (summary) of the procedure in your notebook. Remember to bring your lab manual and notebook to class and wear proper lab attire. Please also bring a calculator (does not need to be scientific). Please study the link on the class web page for Common Laboratory Operations and Apparatus.

Your lab report for experiment 6 will be due. Please read Part II of the Information Sheet before starting the report. Remember that all calculations are to include units and are to be to the proper number of significant digits. Multiple pages must be stapled.

It will be easiest to do the report in 3 separate sections A, B, C as though there were three reports (but one submittal).

A. Chrom.- Raw data: list the stationary phase and mobil phase for thin layer. Give distance traveled by solvent, blue dye and red dye.
List the stationary and mobil phases for the column. Samp calc: calculate Rf for red and blue dyes. Results: Rf values. Discussion: Describe what you saw.

B. Cations- Raw data: Give your observations for each step. Samp calc: Give balanced equations Results: List cations found. Discussion: describe the 3 test tubes that I checked.

C. Ion Exchange- Raw data: Give voulmes, mass, concentratios. Samp calc: Show equation I placed on board. Results: % efficiency Discussion: Discuss result.
