Separating a Mixture using Distillation

Separating a Mixture using Distillation

Today we are going to do a Distillation Experiment.

What is Evaporation? 
Evaporation is heating up a liquid and turning it into a gas. (adding energy = heat)

What is Condensation?
Condensation is the change of the physical state of matter from the gas phase into the liquid phase.

Aim: to separate a solution (Coke/Coke Zero) to form a solid + a liquid

Hypothesis:  I think that the colour dye is going to separate from the liquid because there is a colour dye (caramel colour) in the liquid. So maybe it might turn into a clear liquid? I thought there would be a solid because the liquid evaporated. 

Equipment:

1. Coke + Coke Zero
2. Bunsen Burner
3. Conical Flask
4. Heatproof Mat
5. Delivery Tube
6. Bung
7. Tripod
8. Gauze Mat
9. Retort Stand
10. Boss head and clamp
11. Boiling Tube

Method:

1. Set up the equipment (shown in the picture below)
2. Add approximately 50ml of Coke or Coke Zero to your conical flask.
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 solution has been evaporated and it starts foaming.

Results (Observations) - What did we see?
 - The coke boiling inside the Conical Flask
 - As the water was evaporating it left the sugar behind.
 - The steam went threw the delivery tube into the Tube.
