Aim:

To separate a solute from a solvent in a solution using distillation

Equipment: 

Coke
Two test tubes
Heatproof mat
A delivery tube and bung
Bunsen burner
Tripod
Gause mat
Retort stand
Boss head and clamp
Boiling tube

Method:

  1. Set up the equipment as shown in the diagram
  2. Add approximately 50 mL of coke to one of your test tubes
  3. Light your bunsen burner, open the air hole and gently push the bunsen burner under the tripod
  4. Heat the solution until most of the solvent has been evaporated. Turn off your bunsen burner.

Results/Discussion






Well... hmm.. I forgot to mention that you don't want to boil the liquid... My group accidentally did that and messed up our experiment...  What was supposed to happen is clear liquid would leave the first test tube and enter the other tube. What ours did was boil over... basically, the liquid didn't evaporate it just moved test tubes. 
I mean, it looked cool.










Conclusion: 

Distillation is a process that can be used to separate a pure liquid from a mixture of liquids. We were trying to separate the solute from the solvent in a solution. Some people's worked while ours didn't. Next time, if there is a next time, we need to remember to not overheat the solution!
