After reading pages 626-627, 641-660, and the supplement to Handout 1, you should be able to do the following:
1. Describe the common procedure for determining the melting point of an unknown sample. 2. Describe how an extraction can be used to effect a separation, Fig. 7.1.
3. Define miscible and soluble.
4. Explain what is meant by the following statement "The organic reaction mixture was washed" and understand the purpose of a water wash.
5. Explain why it is better to extract several times with small portions rather than a single time with a large portion.
6. Delineate the steps necessary to separate the lower layer in an extraction, Fig. 7.5.
