1) Why is the column packing material used in the fractional distillation column? 2) What should be the characteristic features of an ideal column packing material? 3) Two fractional distillations are run with identical mixed samples of two liquids using different columns. In apparatus A, the column is 15 em long, and in apparatus B, the column is 25 cm long. Will one apparatus provide any better separation of the mixture then the other? If so which one and why?...

1. A student carried out a simple distillation on a compound known to boil at 124°C and reported an observed boiling point of 116°-117°C. TLC comparison of the product showed that the compound was pure, and a calibration of the thermometer indicated that it was accurate. What procedural error might the student have made in setting up the distillation apparatus? 2. Which method is better for purifying a mixture of two liquids that boil at nearly the same temperature: simple...

rewrite text in past tense Procedure-Simple Distillation 1. Take 60 ml of a 50:50 mixture of cyclohexane and toluene and place in a round bottom flask. Make sure you add a few boiling chips. 2. Assemble the distillation apparatus (See Figure 2.) and start the water flowing through the condenser. Place a graduated cylinder under the bent adapter so that you can measure the volume of distillate you collect. 3. Begin heating the sample with a heating mantle until it...

Begin with a clean, dry 250 mL two-necked round-bottom flask. Add a stir bar and 0.7 g of magnesium turnings. Attach a dry, water-jacketed reflux condenser (also known as a West condenser) and additiorn funnel (you are using your separatory funnel as an addition funnel). You should lightly grease the ground glass joints of your apparatus -...
