Distillation

Today in Chemicals we did an experiment on distillation. Distillation is an experiment used to show the process of condensation.  In this experiment, we're using different types of cokes like normal ones and zero ones. 

Separating a mixture using Distillation
Aim: To separate a solute from a solvent in a solution using distillation.
Hypothesis: I think that Coca-Cola will stay the same, and Zero will just be partly changed. 
Equipment: A solution of different types of cokes, conical flask, heatproof mat, a delivery tube, and bung, Bunsen Burner, tripod, gauze mat, retort stand, boss head, and clamp, boiling tube. 

Method:

1. Set up the equipment as shown in the diagram.
2. Add approximately 50mL of coke to your conical flask. 
3. Start the element.
4. Heat the solution until most of the solvent has been evaporated. Turn off the element.  

First, we had set up the equipment we needed. Our group used the Coca-Cola Zero.

Observation: First the Coke was still and it was just heating up, then it just started to form little bubbles, then it started to bubble up a lot, then it looked like clear water was being sucked by the delivering tube into the conical flask. 

Discussion: In the conical flask that had the coke in it, at the bottom there were some dried sugar left (it isn't a burn mark because if we heat it up it would form bubbles), When we heated the Coca-Cola, it evaporated and it got trapped which separated it, then we used ice to cool it down. I saw steam because it was heating. Our flask had less sugar left over compared to the other group that had the original Coca-Cola that had sugar in it.

But then there was a clear liquid that has been sucked by the delivering tube and I think that it the condensation from the Coca-Cola, I guess there's only one way to find that out, is to look on the ingredients on the Coca Cola bottle. 

Conclusion: This experiment was very interesting and shocking, because I've always thought that the Zero Coca-cola had no sugar in it because it say on the label of the bottle, then doing this experiment shows that there was actually a decent amount of sugar left at the bottom of the flask.
