Distilation

Distillation Experiment

 Today in Chemicals science we did an experiment on distillation.
Separating a mixture using Distillation
Aim: To separate a solute from a solvent in a solution using distillation.
Hypothesis : I think that the Coca-Cola will stay the same, and Zero will change. 
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 set up the equipment we needed. Our group had the Coca-Cola Zero. 

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

Discussion: In the conical flask that had the coke in it, at the bottom there were some sugar left When we heated the Coca-Cola, it evaporated and it got trapped which separated it,  we used ice to cool it down.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 but the results were a little 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.
