Cynthia Bolon 213 Schrenk Hall [email protected] 341-4439 OBJECTIVES: Course objectives are to develop facility with performing laboratory techniques involving the handling of organic chemicals safely and the keeping of proper records of experiments conducted in the laboratory. Crystallization, distillation, extraction and chromatography are emphasized as separation and purification techniques. Melting points, boiling points, and refractive indices are used routinely as measures of purity. Safe handling of chemicals and proper disposal of waste products are priority goals in this course. To help in attaining such goals, the first week of the semester is devoted to SAFETY in the chemistry laboratory. For the remainder of the semester, most of the experiments are conducted on a micro scale.

Gravimetric Analysis of Chloride
Chemistry 321L Manual Page 16 Gravimetric Analysis of Chloride I. Introduction The amount of chloride ion in a substance can be determined by precipitating the soluble chloride ion present with silver ion. The amount of chloride ion present will be related to the mass of silver chloride formed. + - Ag (aq) + Cl (aq) 6 AgCl (s) II. Procedure A. Preparation of Filter Crucibles (Sintered-Glass) 1. Use four filter crucibles of medium (M) porosity. Do not use crucibles marked C for coarse porosity. 2. Previously, the crucibles have been used to filter silver chloride (purple or gray, ammonia soluble). First, remove any bulk precipitate with a rubber policeman and dispose of it in a "Silver Collection" jar. Follow this with chemical cleaning. To remove silver chloride, invert the crucibles in a large beaker in a fume hood and add one or two mL of concentrated ammonia to each. Allow to soak until clean. Carefully remove the crucibles from the beaker and soak in water before removing from the fume hood. Set up a suction filtration apparatus and wash the crucible several times with water and finally with deionized water. Empty the suction flask before proceeding. Stains that are not removed by this cleaning process should not interfere with your measurements. Number, in pencil, each crucible on the frosted glass area. 3. Dry the crucibles in an oven at 120EC for about 1 hour, using a beaker, glass hooks, and watch glass (see figure). A ribbed watch glass can be used in place of the glass hooks. 4. Remove the dried crucibles from the oven and let them cool for about one minute on the counter top. -
LAB: One Tube Reaction Part 1
AP Chemistry LAB: One Tube Reaction Part 1 Objective: To monitor and document the chemical changes occurring in a single test tube containing a predetermined mixture of chemicals. Materials: test tube, iron nail, sodium chloride, copper (II) sulfate, distilled water, glass stirring rod, tissue paper, parafilm wax Procedures: 1. Label a test tube to identify your group 2. Fill approx. 1/3 of the test tube with copper (II) sulfate crystals. Gently tap the tube to allow the crystals to settle. 3. Using a glass stirring rod, carefully cover the crystals with a layer of Kimwipe tissue paper. 4. Slowly, and with as little disturbance as possible, add enough distilled water to just cover the paper and blue crystals. 5. Repeat the process for the sodium chloride, filling approx. 1/3 of the test tube. Gently tap the tube to allow the crystals to settle. 6. Push more tissue paper into the test tube on top of the white crystals. 7. Add enough water to cover the tissue paper and white crystals. 8. Obtain an iron nail and expose the surface by rubbing with sand paper. 9. Carefully slide the nail into the test tube. 10. Continue adding water until the nail is completely covered. 11. Cover the test tube with parafilm wax and record your Day 1 observations. 12. Return the test tube to the test tube rack. 13. Continue to monitor and record your observations for the next several days, as indicated in the data table. Data: 1. Complete the NFPA label for the two chemicals used in this lab. -
