Assemble the glassware for fractional distillation according to the diagram and discussion above. Make certain that all joints are secure and that the apparatus is appropriately supported. Remember to allow for space below the distillation flask for the heating mantle and below the receiving flask for an ice bath. Pay extra attention to the positioning of the bulb of the thermometer as mentioned in the introduction. It is critical that the thermometer be positioned correctly for accurate temperature measurement. Using...
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...

Remember in experiment 2 you used boiling chips; can the boiling sticks be replaced by boiling chips in this experiment? Explain your answer. Experiment2: Determination of Alcohol content of Wine by Fractional Distillation Introduction If a mixture of ethanol and water are warmed you might expect the more volatile (lower boiling) ethanol to boil first and then the water. This is not exactly true. As the mixture is warmed all the molecules within the flask will gain energy. In fact...

Determine the yield of the products.
The first should be the yield of benzoic acid.
The ammon plus is should be the yield of benzamide. Please
write out and show all work, theoretical yield etc. Thanks!
Purification-Week add Decant the dry dichloromethane solution into a 25-mlL round-bottom flask, and a few boiling chips. Don't worry if a little magnesium sulfate slips into the distilla- tion flask, it will act as additional boiling chips. Set up an apparatus for microscale simple...
