Part V. Experiments 28 Fall 2010 E. Objectives: 1. To master the technique for measuring melting points in capillary tubes using the Meltemp apparatus. 2. To determine the similarities and differences in the melting behavior between pure solids and mixtures of solids. 3. Consider what the melting point behavior of a sample of an unknown solid might suggest about the composition of the sample. F. Key Terms/concepts/techniques: • The Melting Point: • The Meltemp Apparatus
Fall 2010 29 Part IV. Experiments Experiment 5 Part A How Can an Impure Solid Substance Be Purified TLC CHROMATOGRAPHY A. Pre-lab Preparation Assignment: 1. Read: This handout 2. Read: Chromatography (Padías pp. 150-151) Thin-layer chromatography (Padías pp. 153-160) 3. Work through the material and links on the Experiment 5 Part A page of the course website. 4. Complete the electronic Prelab Questions (course website) by 8:00 PM, Thursday, October 7 on the Course Blackboard Site as explained on the Course Information page. 5. Consider possible claims and warrants relative to the QOW (See below) 6. In your lab notebook: (See Lab Manual pp. 15-17 for format.) a. Enter the title of the experiment and QOW on the appropriate first left-hand page. b. Up-date the Table of Contents. 7. Bring your notebook and your initial claims and warrants concerning the QOW to the AM lab discussion on Friday, October 8. B. Objectives: 1. To review the use of melting point as a measure of purity of a solid substance. 2. To master thin layer chromatography techniques for separating and analyzing solid organic samples. C. Question of the Week: How can we judge the purity of a sample of an unknown solid compound D. Key Terms/concepts/techniques: Thin Layer chromatography • Ascending vs. descending chromatography • Capillary action • Application vs. development vs. visualization vs. identification • R f values
