    Problem #1

    After completing this problem, the student will be able to:

    1. Devise a scheme to be able to isolate organic acids, bases and neutrals through an extraction process.
    2. Devise a scheme to be able to extract metal ions into an organic phase.
    3. Predict the general effect of pH on the extraction efficiency of a metal ion into an organic phase.

    Problem #2

    After completing this problem, the student will be able to:

    1. Devise a scheme to be able solubilize an organic ion with a lipophillic component into an organic phase using ion pairing.

    After the introductory lecture material on chromatography, the student will be able to:

    1. Write the expression for the distribution coefficient
    2. Write the expression for the partition coefficient
    3. Describe how paper and thin-layer chromatography work
    4. Write the definition of adsorption and partitioning
    5. Describe the procedure for coating a liquid chromatographic phase
    6. Write the expression for the selectivity factor
    7. Write the expression for the retention or capacity factor
    8. Describe the concepts of a theoretical plate and height equivalent of a theoretical plate
    9. Write the expression for the resolution of two chromatographic peaks
